[1.1.0] Crash when autosaving (DifficultySettings::save)

[wsvolt]

After switching to 1.1.0 and moving my old save over (pretty new, created on 1.0) the game now crashes when attempting to autosave but appears to only be when writing to the third autosave file as _autosave1/2 seem to be saved correctly. Log is attached as well as the .tmp autosave file which wont load in game.
