There is nothing wrong with the code that I can see. I'll play the part in Steam and see what happens.
Edit.
Yeah, there is a problem here and I am not sure what it is. A big oversight nonetheless.
Edit 2.
Still can't work it out
But I will.

This is a bitch. The code is the same in the original and in mine where it matters. It gets to the part where it has to jump to another map (which is where the movie is told to play from) - and then boom. Crash. Everything suggests that it really should crash on both - or neither.
Edit 4.
I've been checking now and then and I've ruled out everything except a problem with touphScript or Makou Reactor
Luksy/Myst6re will be ecstatic if I am right. Basically, any jump to blackbg9 is failing on the modified flevel I have. The code in it is the same so no crash should occur.
I will have something to eat and narrow it down further. The issue definitely doesn't seem to be down to my code.
