i think! mine did that too (i use the chinese version so sorry if my egnlish isn't that good)
I am stuck on save files i think i need to restart the game to do it
If you're having a lot of trouble playing on a PC, I recommend using Joiplay(smartphones)! I managed to play Shift 1 and 2 on that emulator, I can't guarantee it will work with Shift 3! I'll test it now and delete my old version of the game.
