[0.98.1] Crash when attempting Autosave

[landscribe]

Game is crashing periodically, suspect it might be as an autosave tries to start.

There are no recent autosaves in my load list (since crashes started happening).

I am deleting all autosave files to see if that fixes the problem.

Crash log attached, although it's saved as [0.98.0].

Deleting the existing autosaves appears to have fixed the problem.

Also experiencing the same issue with experimental 98.8. It seems like whenever the game tries to override an existing autosave, it crashes. (Strange the same thing doesn't happen with quicksaving.)
