Hi, I have the same problem than @vagrant cipher I found the F letter in the toilet seat, however it somehow disappeared, and I can no longer find it in the toilet anymore, or on the fridge. BUT for me, when I launch the last saved game no change is produced, there is still no F that reappears on the toilet. Help me please ...I'm blocked in the progress.
#The F letter has disappeared, it does not reappear despite my game reloads.
