I've logged a good 15 hours or so into AA and have never had a problem, until tonight. Every time I've tried to play AA, it'll start with IMMENSE lag but will smooth out, after a minute or so. After no more than 20 minutes of playtime, the game freezes and crashes. I haven't downloaded anything new, since I started playing AA and there's nothing specific that seems to be causing the crashing. The only thing I can think that MIGHT be causing it is that recently, I've somewhat cornered the USAF into one small town and they're pretty agro (lvl 10, right now) so is it possible that there's too many AI in one area, doing too many things and that causes the game to crash?
