Alright, I think I’ve found the problem.
Have you considered a scenario where both conditions – *if (no = true) and *if (funnybusiness = false) – can’t be met at all?
The code won’t find a way how to continue, and thus, “Illegal to fall in” error.
As a note, @Bathala’s way of handling *if , as in
*if (condition)
#choice body
choice text
is preferrable to avoid quicktest/randomtest issues.
Oh. By the way, since you’re seem to be in early stage of writing, I recommend looking into Implicit Control Flow feature CS has.
