NPE Error when clicking signs in random world

[ParadiddlePride]

Hello, I would like to preface this by saying the worlds are being generated by a plugin called DungeonsXL (link here). I don't use signs for Wild-TP but created a GUI for it which runs fine. The error is thrown when players interact with signs created/used in DungeonsXL inside of one of the dungeon worlds.

As the other plugin creates temporary worlds that only exist while the dungeon is active, I'm not sure if writing possible names in the WildTP config would help. Is there a way I can tell it to ONLY listen to certain worlds?
