Hi, since I've added this mod, players can do PVP on the worlds with PVP disabled.
I know that PVP is disabled because they can't deal damage with other things except from melee attacks, and if I remove this mod, they can't PVP...
I've tried disabling PVP via server.properities, using Nucleus to remove the PVP on a world, and using Universe Guard 2 to create a region disabling PVP on that region, with 0 results.

There's any way to solve this problem? It's creating a big problem on my server
