I was recently made aware of an issue with the Queller AI and the Play From Here feature in Chronocam. This is a button that allows you to rewind the game to specific point in time and resume play. Unfortunately, for some reason this causes Queller to exhibit odd behaviours, such as failing to expand and failing to attack. For the time being I would advise not using the Play From Here button in conjunction with the Queller AI.
Version 4.23.0 - 2018-03-24 Additional language translations: Korean (ko) translation courtesy of R.O.S.S Uber Legion will use a small number of Monstrosities balanced against its advanced bots Fixed subpersonalities not teching at the same speed as Uber Uber Cautious will tech as quickly as Uber Tech Properly exclude hover titans and Locusts from hover platoons Changed how Locusts are used to avoid them engaging units Uber less likely to use support commanders Lower the number of factories Gold and above can use to make Locusts Uber makes greater use of turrets around its MEX Uber doesn't place MEX defences as close to the main base Uber tries to place defences to deal with Locust threats Gold and above properly check energy before building orbital scouts Uber favours the Catapult over the Advanced Laser Turret Uber checks advanced units are around before building Decimators Casual through Silver should never get stuck on their starting island Don't rush for a T1 naval factory if a T2 naval factory still remains Won't keep building units to clear mines when the enemy's planetary presence has been removed Corrected Gold Legion not building certain units for invasions Gold Legion is a little more selective with its advanced unit mix Casual will build fabbers even when under attack Bronze won't build fabbers when its base is threatened Platinum uses less Deathmarks Platinum and Uber no longer build Locusts in the Unit Cannon Uber produces less Bluehawks in response to orbital threats When thinking about Bluehawks and Panzers Uber will only worry about the local orbital threat when still fighting for the planet Platinum and Uber check that an air threat exists before building AA for invasion forces If alone on a planet don't build troops unless there is somewhere to send them so as to save the sim and free up resources for other purposes Corrected what appeared to be errors in Uber Bot's T2 Legion choices Ensure proper chance of Uber MLA teching to T2 tanks when alone Move Locusts between planets Minor changes made to various checks to try and help performance Fixed difficulties below Uber not assigning Levelers to platoons Fixed Levelers not being sent through teleporters Uber no longer requires a base amount of vehicle fabbers Allow Uber to build Tyrs on multiple planets at the same time Reduced Uber's usage of Anchors and Centurions to defend ground bases Allow Gold and above to use Anchors and Centurions across more of a planet Stopped Umbrellas including anti-ground defence in their placement calculations Uber tries be smarter about when it needs certain anti-orbital units Never have orbital scouts or radar perform recon on a gas giant Allow building of amphibious bots again due to land pathfinding detection sometimes failing causing factories to idle Restore old defence placement method to reduce undercounting of defences Uber won't use more orbital fabbers when alone Setup lobby messages to work with translations Fix for orbital units never leaving gas giants Gold more aggressive about their gas giant expansion Combined some orbital defence checks for performance Less orbital defence at most levels Uber uses less orbital fabbers outside gas giants Orbital factory builds no longer block land factory builds Gold and above choose between T2 factories or Unit Cannons to ensure focused builds Uber Cautious is now Uber Free For All Uber Free For All is less cautious Don't build a transport for Commander evac if a teleporter is available Won't allow gas giant attack bug to trap it in an anti-orbital build loop Gold and above no longer increase the naval fabber to factory ratio when alone on a planet Uber Free For All doesn't prioritise early air as highly Place artillery slightly within max range to account for interference from planet curvature Uber less likely to build Solar Arrays Gold will tech if it can't expand Gold won't rush a nuke as early Gold and Platinum prioritise a teleporter over a factory when arriving on a new world Uber uses a new method to determine the risk of nukes it hasn't scouted on other worlds existing Casual, Platinum and Uber more likely to use a planet splitter titan Uber Legion fabbers now properly aligned with the Commander on when vehicle factory builds should occur Don't form a land platoon if the only thing available to attack is naval Uber doesn't mistake T1 artillery for T2 when placing Ramparts Uber accounts for the difference in range between MLA and Legion artillery when placing Ramparts Don't make the Odin turn as much due to low turret speed preventing it from tracking Fixed error where Uber was placing defences outside of shields instead of inside them Uber Legion uses less T2 defence at each location Uber more likely to use Decimators when it has Ramparts Ensure that on arriving at a new world a teleporter is always placed before a factory
Version 4.24.0 - 2018-03-27 Corrected issue on naval maps which could cause Bronze and Silver to not produce fabbers Bronze now spaces its defences Corrected inconsistencies in defence spacing Allowed tighter placement of anti-orbital defences Bronze will build the Hive on the perimeter Fixed Uber not building the Laser Defence Tower when it was supposed to Corrected errors preventing defence placement in certain circumstances Changed how each difficulty detects where it can place defences Bronze and Silver try to avoid placing laser turrets on water Consider more than just land threats when placing Ramparts Push Uber's MEX defence further from the base again Uber slightly more likely to use the Single Laser Defence Tower and Jackal Fix Uber Legion not putting Tolas by super weapons Uber more likely to put AA by MEX
Version 4.25.0 - 2018-04-03 Fixed an error in Uber Air's economy handling Updated Uber Rush to make use of multiple Commanders Fix for Legion Commanders not leaving their starting planet Continue to build basic energy into the late game Uber Legion checks it has enough fabbers before having them build energy Uber more likely to throw additional resources at building nukes Uber less likely to throw additional resources at anti-nukes with a missile in the silo
I suppose more accurately it's "Increased priority Uber gives to going orbital when its criteria for when going orbital are met". It still tries to be smart about it, it's simply that once it thinks it should go orbital it won't spend so long dicking about.
Version 4.25.2 - 2018-04-08 Updated German translation with thanks to tunsel Corrected some issues with Uber Legion's nuke builds Uber won't build long range artillery in reaction to naval any more

Version 4.27.0 - 2018-08-27 Uber doesn't run its energy as tight Corrected an error in Uber's energy handling Lowered priority of building factories specifically for AA Check Advanced Vehicle Fabricators can move around before Uber builds them Improve how Uber's Commander protects itself from air snipes Uber MLA uses far less GIL-Es Uber MLA uses less Bluehawks Reduce the amount of T1 factories constructed as an AA measure Uber Legion won't build more T1 bot factories for AA if it has a T2 bot factory Uber MLA Free-For-All uses less Locusts Uber MLA never uses GIL-E for AA Uber MLA less likely to build Colonels Changed how factory build checks are performed from Silver upwards to encourage more builds and help performance Corrected some build condition name errors Uber's Commander attempts to better protect itself against Boom and Purger snipes Uber avoids building land factories using air fabbers as the initiating builder Uber more consistent at teching Uber will build more advanced naval factories in ponds Uber MLA more willing to go tanks on planets it owns so as to increase likelihood of Levelers Removed Uber Tech personality Removed Uber Land personality Uber Free For All won't use fighters for scouting Remove some checks which stopped Uber Free For All from using tanks when it should Uber Naval uses more Krakens Separate Kaiju from naval platoons again to prevent hording when facing sub fleets Uber assigns less fabbers to metal expansion when alone than it did before Fixed Uber Legion not properly checking for advanced metal extractor possibilities when alone Uber Naval builds an advanced naval fabber before advanced offensive ships Further delayed Uber's building of advanced air Uber priortises metal expansion over energy Uber Free For All is a little less expansive Uber Air won't open with air Uber more likely to produce Spinners when sighting air Reduced the percentage of Uber's land forces comprised of mobile AA
Version 4.27.1 - 2018-08-28 Fixed issue causing Silver, Gold and Platinum to keep orbital fighters on gas giants too long Fixed more build condition naming errors Fixed lobby version chat message being incorrect
Version 4.28.0 - 2018-09-03 Casual, Bronze and Silver won't build most defences or artillery when alone Casual places less Umbrellas in bases Bronze won't grow its air presence when alone on a planet Casual, Bronze and Silver won't grow their naval presence when alone on a planet Casual and Bronze won't build Halleys on their main eco planet Casual more likely to build Unit Cannon Casual will send Manhattans through teleporters Casual, Bronze and Silver now rush anti-nukes when necessary Fixed the amount of anti-orbital being placed by Legion at low difficulty levels Reduced the amount of orbital defence placed by Casual Fixed Causal, Bronze and Silver not properly using hover units Properly exclude hover units from offensive scout platoons
I've amended the recommended difficulty values for Gold ranked players and above in the OP due to Queller getting better.
Version 4.28.1 - 2018-09-07 Bronze, Silver and Gold now always make sure to check if a naval route is available from a naval factory Allow Uber to build advanced air a little earlier
Version 4.29.0 - 2018-09-13 Panzer builds at Uber level properly updated for changes to anti-air ratios Uber builds less Deathmarks Uber builds more Scorpions Improved checks for lava Uber builds less Monstrosities Increased chance of Uber building an Ares Fix for Gold and above getting in situations where they wouldn't scout orbitally Tweak to teleporter placement Gold won't build Locusts in Unit Cannon to work around an issue which caused them not to fire Uber builds more Minimen in response to Scorpions Uber won't build Praetorians in response to non-Titan air Uber Naval puts greater emphasis on T1 naval when it's fighting a sub war Don't look for naval build locations using land fabbers as it's rare enough that it's not worth the performance cost Capped the number of naval scouts Uber will use Uber won't build Hammerheads when it's losing the sub war Uber forms larger naval platoons for Legion when using Catfish Don't treat Kaijus as artillery Don't count Talos when forming offensive naval scout platoons Fixed hover units not being excluded from offensive naval scout platoons by Silver and Uber Uber uses a higher number of Peacekeepers in its early game forces and maintains a small amount later on Expand lobby message to cover AI best practice Removed remaining references to Uber Land Fix for Gold, Platinum and Uber building too many Marauders at once Fixed Uber Tank not working correctly when playing as Legion Prevent Corsairs being put in the wrong squad Uber Naval will build air second with Legion as it doesn't have access to Patriots Uber Naval is smarter about meeting its fabber requirements
None of the other levels put Locusts in the Unit Cannon. I reproduced the problem with the vanilla AI. If you load all Locusts it's fine. All units except Locusts it's fine. Add one Locust into a non-Locust mix though and the cannon "jams". I suspect it's something to do with how the UnitCannon task interacts with platoons, as both Queller and the vanilla AI exclude Locusts from army platoons. A bug has been raised within Planetary Annihilation Inc around this.
