I was in MP and I alt tabbed and game crashed. Chance it happens is 1 from 50 when going to windows.
- Legacy ID
- Game Crash
All logs you need are included in Arma 3 Alpha.rar
seems to happen when steam community is enabled for me, fixed it by disabling it (could be related to something else too but that fixed it for me) after having 40+ hours played and probably a few hundred alt tabs (making a mission)
