Hey
@ays. Are you using doggi's mod by chance?? or did any other editing of the random event chance checks??
As far as i can tell theres a difference in the code terminology used for that last entry in the random chance lists.. which is nora_schoolgirl_check. In the vanilla file from the download, it has it as nora_schoolgirl_check, from doggi's custom scripts.rpa file.. its listed as nora_schoolgirl .. without the _check part.
That might be why you are getting that error then.
I only noticed as im going through the changes myself line by line (and making some edits of my own) and i saw your post.. and i was confused cause (even though i understand renpy scripting very little) what you said and what i saw as the variables/values looked right, yet then i checked the corresponding lines in doggi's mod and saw the difference.
