Just be mindful that there is a persistent variable that attaches to the save file itself, so an older version may not necessarily help.
So i must NOT copy any save files from 0.46->0.45. Or reinstall 0.45.2 without any Saves. Thx for the warning.
Failing that i can still delete all saves including the %appdata%

Hopefully this should work.
