Well, I'm still mystified at this stage. But keep looking, let me know if you find anything unusual. Try to pin it down by save-walking if you can.
save-walking doesn't help. I save manually every 12 ingame hours. When I reload a save, it just keeps going, until it crashes after ~30 minutes. No spikes in CPU usage, RAM usage and/or temperature.Have you tried setting the popcap to something like 25 or 50, and seeing what happens?
just tried it, with settings to 25 and 50. Still crashes. But it seemed, that the game lasted longer when I set it to 25. Could play for an hour. But I had it on pause for a fair bit of the time, too.
I also activated InformOnStoryAction. There were several actions in the play time, like Romance, Skill or Work, but nothing specific at the crash time. Maybe the culprit is a stack, which is overflowing or something like that? I currently don't have my desktop PC ready, otherwise I would test it on that one, and my gf won't let me install it on her computer.
The Crash Log Analyzer says the last two were a "Corrupt Save Crash", while the ones before were "Unknown". I'm going to start a new neighborhood tomorrow.
I am currently uploading two savegames:
Twinbrook, where I experienced crashes and had several options enabled.
Twinbrook - AMdis, where I tested with all options off. This is the one, where I got "Corrupt Save" crashes.
Maybe this helps figuring out more.
