So, I have been a fan of LoSeSb for quite some time, and I never had problems with it whatsoever. I had used cheats and had been editing the variables via the consoles, but here too, no problems. When I got the newest update (upgrading from 20.11.1d to 21.2.1a) I was switching my Heroes personality. Instead of playing as Mike, I was playing Mike, just without the Grils. Also, there was another Mike, in another Mikes bedroom. I could kiss him, and as I did, I was Bree. When I was loading the save with my last version, everything was fine. When I was playing an old save on the new version, saved, and loaded that with the old version, everthing was fine again. Reinstalling the new version didn't help either.
I hope it can be fixed (if this is my part), because I don't want to start a new run yet again.
I've attached the traceback for the error I got when loading with the new version (I clicked ignore and rollback in game, with no differing results).
