I've been getting a crash to desktop error lately in my playthrough; anytime I research the plasma rifle, try manufacturing buzzard armor, or even just detect too many UFOs at once, it crashes. Still testing to see if this happens with anything and everything, but regardless I can't seem to get past November 12th without the game murdering itself. Save file here on Dropbox; I am running a somewhat modded game, using the Alien Class Analysis Mod as well as the Community Map Pack and Stinky's Maps. Other than that, it's a clean game, no personal tinkering or such.
Really hoping there's a workaround, seeing as I've never even seen December before because every experimental build likes to crash before then
