The game freezes up then eventually it says lost connection to server. After that the match is gone and the main menu is displayed. I've updated my drivers, like SXX suggested. I think this may be related to the number of units. I was issue orders to a huge number (I don't know how many--possibly 400-600 units total) of vehicle units when it happened. Also, I had a large number (200-300?) of orbital units doing things as well. It was a single player AI Skirmish, set to private, FFA match with 3 AIs set to hard, and one was killed off already. There were 4 moons (not movable) circling a gas planet. It was a generated system and not a custom one. Log attached.
Do you have any software on this list? http://steamcommunity.com/app/233250/discussions/2/558751813508748383/ Specifically, any VPN software or stuff that messes with networking?
How often does this occur for you? Does it also happen when you turn off the local server in [SETTINGS] -> [SERVER] and use Uber's servers? You'll be playing on-line of course, but this is just for testing purposes. If that crashes as well, then there is simply a bug in the server code. Luckily crashing Uber servers generate debug dumps for Uber, so they can track the bug down. Post the lobby ID of on-line servers you manage to crash. If Uber's servers don't crash on you, then it must be something specific to your computer and then we need to track that down instead.
Not often. I think it's only happened twice out of many games. I have not tried using Uber servers. I will start using them to test.
