Do you have the latest version of the game?
If yes, can you try sending me your save file? That randomly-jumping-to-foreplay bug should have been fixed, but it might still affect it if you use older saves to continue your play through.
I just bought the game 10 days ago and downloaded it then so it should be the latest version. Sorry, I deleted the messed up saves when I tried the save I made at the festival and it didn't go to foreplay mode. I lost a month of progress but the game seems to be working fine now. Should I re-download the game and start over?
