I just checked Hidden Biomes and it seems to still be good. Make all the sandbox planets you want. https://forums.uberent.com/threads/rel-hidden-biomes-1-2-1-86765.64250/ Idle just sets eco zero in server script, so I didn't see much point.
The point is that if I put the enemy on idle, the eco multiplier can be 1, which means I can give the idle ai some factories to build stuff with
Ah, the econ-0 method was removed a month ago in 84088-pte; I missed it amongst the commander overhaul.
Instant Sandbox 2.8.0 - "Idle" available for personality setting (new default), which doesn't affect eco rate since 84088-pte - Default eco rates set to 1.0 @dom314
Instant Sandbox 2.9.0 - Try to use information from "Favorite Colour" mod for player and first AI - Reduce output to debug console - Fix mounting server mods in certain circumstances
The settings on the gameplay tab are no longer properly aligned. I'm assuming this has been the case since the changes to the page in 113945. Legion was showing the same issue and it was fixed in this commit. There also appears to be an issue with the page not using a scrollbar when multiple mods edit the page (which I'm sure it used to), but I'm not sure if that's something mods need to be modified for or a core game issue.
Is Wondible still around? I would like to see the enemy AI changed to IDLE and 10x econ bonus so i can test radar, builds, and units that consume energy. EDIT: I just found the instant sandbox settings, while most of the settings work, the AI personality is ignored and they build and play anyway, I wonder if its a conflict with another AI mod like Queller-AI. Also the player/AI econ rates can only be set up to 5x which is strange since the default player econ rate was 10x but I can no longer get to it. (I would also recommend a button alongside 'Set System' that has 'Default Instant System' because finding that planet in the shared system files is a pain)
I usually use Idle, so it's either a very recent change or another mod. It's been years since I was at default settings, but that does seem off. I have a couple testing systems depending on what I'm doing. I do tend to return to my minimal system, but it is hard to say if that will be suitable to everybody.
Instant Sandbox 2.10.1 - Fix heading in settings screen - Fix stuck on publish game when starting sandbox game first thing after launching program.
