I am having a little problem with a victory condition occurring when the first Doom wave is destroyed. At least, that seems to be what causes the end. Disabling Doom wave keeps the game going. I have endless normal and boss waves enabled, and Doom HQ damage set to 0. 3-4 Dooms per wave.
By the way we have had some additional problems with the game going into that freeze condition with the UI and chat still responsive. I think it might be related to waves spawning in. It seems like if fewer units are in play, it doesn't happen.
And also, there has been an appearance of a strange bug seemingly related to pathfinding. Air units will fly like 20x higher than usual and take minutes to come down to attack. There will also be an invisible vertical map barrier that land units can not cross. Very strange. And a game restart usually fixes it even with identical settings. Maybe it's related to the recent FAF patches.
