Is there a way to test what you guys are doing on a new save without the crack, or is it too far into the game? Because that would be an easy way to rule out the crack.
Can either or both of you DM me your save file and tell me exactly how to reproduce what you are talking about (as I haven't played the game so I don't know what it is you are doing)
I will investigate if this is actually the crack causing this or not, which I'm putting my bets on it isn't.
Do you have any proof of this, or just blaming the crack because some early access, beta version of a game can't have any bugs, right?
