IDK what is going on my end, but it happened again the next day and I am guessing it will happen again today but here is what I did:
I cleared temp files in both folders, uninstalled, rebooted, reinstalled, rebooted, tested and it didn't do that anymore.
What I noticed is that when it happens, it does so at the moment it autosaves, IDK if there is an option to disable auto saves while they correct it, I will check, but yeah, last time it happened I had just finished the hacking of the antenna in the hedge and as it was autosaving this happened, and then I reinstalled and rebooted and could play for hours... but it is not actually sensible nor acceptable to just reinstall every day hahaha
