Remove Pixelmon.

Haha, but kind of seriously. When/how is it caused (specifically)?

All I see from the log is that it’s sometime when you drop an item, and somethings not going right with sponge. But what item, where, etc?

Word from the wise:

If you see a ConcurrentModificationException (CME) and the CauseTracker in it, then a mod is definitely changing the world one way or another in another thread. The world operates in a single thread environment and Sponge takes that assumption to heart, so a lot of the systems (including the Cause Tracking System) treat all functionality in a single threaded mind.

In this very specific case, some mod (probably pixelmon) is causing block notifications to be thrown in another thread.
