I'm having a problem with the cs,

Spoiler below!

every time i try to go down the Pearl Wing the game crashes and says there's a "Fatal Error: Could not load script file 'custom_stories/map06B.hps' ExecuteString (1,1):Err: No matching signtures to 'OnLeave'()' main(459,2):Err: Expected expression value"

Honestly I don't know what to do :I i even tried redownloading the cs
