Autosave failure then crash

[Dunkhan]

Describe the bug

The autosave function starting generating errors saying that it could not write the file. Unfortunately I kept playing and ignored it. After a few failed saves the game crashed and was unable to be loaded.

Steps To Reproduce

Not known.

Expected behavior

There should be no error messages, the game should not crash, saves should be able to be loaded.

Additional context

Here is the crash on loading the save: https://pastebin.com/4RAnCLHr
Here is the debug log: https://pastebin.com/Abc4S2B1
Here is the save: Bethel Acres.zip

I had tried to set up a base camp at one point (the stack trace says something about basecamp) and had designated a tree cutting zone, a farming zone and a food zone. Not succeeding in working out what to do next I abandoned the idea leaving the zones.
Some time later I was inside a building and my npc went out to investigate a noise. I had forgotten to set him not to (can we change it to default?). He died and then I started getting messages that I was stealing when I accessed my shopping trolley, despite the npc never having touched it. I mention all this because I feel like a strange bug shortly before a crash could be relevant.
