Hi Indivi,
I ran into a problem when trying to load a savestate where my character is wearing a vibrating dildo.
I still had an earlier save that was from about 2 minutes earlier where i wasn't using a dildo, but this might force some people to load a save from much earlier, and thus losing a lot of progress.
Edit: I did some more testing and found out that the game shows this error every time the dildo would be visible. I tried putting it in while wearing a dress and it worked, but it gave me the error when i changed to something that makes the characters pussy visible again.
