--- Comment #22 from James Edmonds james.ytedmonds@gmail.com --- I can confirm this bug for Supreme Commander: Forged Alliance (Stand-Alone expansion, they run on the same Engine. They are treated as the same app on appdb) on wine version 3.5 (instaled through the winehq repos).
I have tried running the game on low settings, it might delay the bug (possibly moving it from occurring after 5 minutes to after 10, have not performed enough testing to find a mean time). I have found however that the bug occurs more quickly on large maps. To reproduce the bug quickly an 81km map (like betrayal ocean or debris) should be loaded with all bot slots filled. I tested with a friend on a 5km map (smallest) and with max unit cap and found that even with 4000 units in game the game does not crash. But 81km map with a fraction of that many units crashes. I have run the game with and without mods and the bug remains the same. Uploaded brief excerpt from the terminal when the bug occurs. If there are debugging tools or command line options I can run wine with to get more verbose output I can reproduce.
