Achievement fix

This is just a quick fix which will hopefully resolve players getting all achievements as soon as they start the game. The problem seemed to be in the fact that we included a persistent save file to the build while we tested the latest update. This was a persistent save from our own files that we should have removed before uploading the build on Steam.
We apologize for the inconvenience. Hopefully, this issue is resolved now. For players who have already faced this bug, we also apologize. Sadly, there is nothing that can be done to reset those achievements.
Again, our deepest apologies for that.
