Is there any source on BGT chapter numbering? For example, if I want to say "after Underdark" in BGT environment, which value in GlobalGT("Chapter","GLOBAL",???) I should use?
Edit: actually now that I have thought about it: does BGT changes chapter numbering in BG2 at all, or it just builds up chapter number during BG1, then resets it, and builds up again from chapter 1 in BG2?
