Actual Behavior

Whenever I place, break or interact with a block/item my console spits out an exception

Expected behavior

Not spamming the console

Steps to reproduce

When I run the server and join and interact with anything

Suggestion on how to fix or supply fix

I assume this is either an issue with Sponge or how one of the mods/plugins is interacting with it
