Edit: Added pastebin link to the error message

Looks like an issue with InteractiveChat. Doesn't seem to be anything with PL

Sorry for the mess in the error code, i copied it to pastebin and heres the link:

I reported the issue to the the author of InteractiveChat and it turns out it's Spigot's problem :P
Anyway thanks for replying and I'm closing this issue. :)
