I should note that it's not like the skip function doesn't work, but skipping over a longer period may, just may, be the cause.
Skipping for a short amount of time, then stopping, then skipping again seems to work? Although I'm not sure. It's kinda tricky, because we get no feedback like an error message. The game doesn't even seem to freeze when the save function borks out and the game becomes unresponsive to any user input. Task manager says the game is still running correctly.
