Hey Sneaky, It's been a while since I used It's A Trap, but have you installed the module for your game system (5e, pathfinder, etc)? I believe the base It's A Trap just does the sounds and layer control. For Door Knocker, I can speak with more assurance. As Matthias said, the token itself isn't actually necessary, it simply links to the Door Knocker Character sheet. If the script can't find a Door Knocker character, it'll make a new one. You'll probably find it at the very bottom of the journal tab. If you can't find it, PM me an invite to your game and I'll do some investigation.
