[Slanderous]

You should try adding debug messages (if you have dev environment enabled) or just something to indicate if this event is executed. Using those you can trace back to where it stops working.

The script does look fine though. Perhaps the problem is that the file isn't loaded.

Fuck, adding debug message helped me again, like in my lever problem :o
This is seriously paranormal, anyway thank you guys for helping another soul!
