This mod has worked great until now, including in 1.1.91.
This morning was prompted by the auto-updater to update the base game to 1.1.94.
Now every time I try to use this Quicksave key, it fails with an error:
Cannot save map: Opening package / _autosave-quick2.tmp.zip for writing failed
Included tested by manually downgrading to 1.1.91, starting a new Map, works fine. Re-open in 1.1.94, errors.
