Its really late so please excuse my abruptness: this script has worked before but now it doesn't. It runs on a container so I never needed to explicitly set its reference in the script. Anyone got any ideas why? Nothing is printed and the game CTD's instantly.

Glancing at the script it looks like you would have multiple message boxes per frame; isn't that one such cause of instant CTD? I can't recall if it should still print the first message box before crashing, however.
