Hmm, I'm not able to reproduce this when loading the save on my system. The next time it happens, can you upload the output_log.txt file (it's in the same folder as the save file)? If there's an uncaught exception it will record in there but it gets overwritten every time the game is started so it needs to be recorded at the moment of the crash.
It still crashes quite instantly on my end.
Sent it to the same Gdrive folder, thanks!
Edit: After sending in the .txt file, tried continuing the game by spamming W, while constantly checking whether the police station is closed down or not. After 2 months or so, the police station didn't open up yet, but I have soft locked on the legislative agenda screen where f1 and continue are pressable, yet nothing happens.
I've looked into this a bit more and I am able to reproduce it locally now, it seems to be an issue that only occurs in the build, not in the editor, which is why I wasn't getting it before. It's an odd issue that seems to be related to some very specific C# functionality so it might be a little bit before I can figure this out but I think I have narrowed down the cause for it at least.
