Null pointer errors with Hexxit Server

[TDKPyrostasis]

Didnt see a specific place to post this.

I'm a youtuber that just started up a Hexxit factions server for my subs. We're running the latest hexxit version and MCPC.

We're getting chain crashes with nullpointers and what looks like water flowing issues. Any ideas?

Here are the three crash reports we had about twenty minutes after opening the server to the public.
