Hey MrsFlynn, sorry to revive such an old topic...but I might have good news. In December of 2022 I accidentally reverted my computer to an old backup of Windows 10 and I actually lost the up-to-date version of Windows 11 entirely. That said, TS3 itself also seems to have gone back in time and the save I have related to the problematic save appears to predate the crashes, soooo that's probably a good thing.
