So I've been using this script to no problem for ages and suddenly just now I'm having this error when after beating the third boss and as I change to stage 4 in Moghunter's Stage Select.
Scripts 'Lights' line 1062: NoMethodError occured
undefined method '[]' for nil:NilClass

EDIT: I think the reason is because the boss map has two torches while the stage 4 room you go into has none and this causes it to bug in the transition, I temporarily removed the torches and the error doesn't appear. How do I get this to work with the torches though?
