I started having crashes on experimentals, too, for the first time, about 4 weeks ago. I haven’t even played in a while either, partly due to the damn crashes. I tried to attribute it to burning buildings, failing roof collapse (since I only play Really Bad Day starts which involve a burning building), but it’s anyone’s guess what causes the crashing. The game doesn’t create a log or anything either. FWIW, the only mods in common that I have to the above are No Joke Monsters and Tanks.
The second suspect that I have is the map generation logic. It’s been a PITA for others too, ruining scenario starts. Once I had a refugee center that was partly replaced by swamp terrain. (Also, in another gameplay video I saw the refugee center being partially replaced with crater). The refugee center merchant character was physically accessible from the swamp side, and he died a few moments later after being attacked by some critters. Put up a good fight, though. I mean, stuff like that… One would think that first the terrain is created, then come the buildings, replacing the terrain. Remove lava streams from cities… What is the map generation logic anyway? What’s the big picture?
I can’t even remember what the Windows crash error message was. Application has crashed yada yada?
I would love to know if anyone has a completely crash-free Cata experience, and what the recipe/setup for that is!
