Awesome good job @TylerS1066 , because Its also stopping Voting plugins depositing keys! I came to post another error haha

I also use DLTTradersPlus!

Any idea if we can get this merged and a jar created?

It's up to @eirikh1996 to merge the PR, but in the meantime here is the jar I've been using without problem on my production server.
