Hmm... I see... I think it might be some change in variables that I made that might be conflicting with what you already had. If that's the case, I apologize, my lack of experience means I don't have much of an idea of when things will break like this :(
My suggestion is a new save to test maybe? (I honestly have no idea if it would solve the problem)
I'll do some tests on this specific version and if I find anything I'll let you know!
