Where are you installing the game (on the disk)?
Maybe it’s some kind of temp folder that gets cleaned after, try some dedicated ie. ~/Games/{game}.
Also, do you keep game files in the prefix or outside it?
I keep my game files outside the prefix, so if you decide to change it, you don’t have to reinstall if something goes wrong. I never had such issue.
