Issue
Trying to use an OpenBlocks XP Drain on top of a Mekanism Basic Fluid Tank while on a server caused the server to crash pretty much instantly with this crash report. I only have one PC so I cannot test any further without severely inconveniencing my players.

To be honest I just don't think you should attempt to put an XP Drain on anything but an OpenBlocks Tank :P

I left a crash report with OpenBlocks and Mekanism devs so hopefully it gets fixed. The drain seems to work with everything else I've tried though

Oh, I see. Well thanks for doing all the work :D do you mind linking the issues here?

No problem

(I apparently forgot to report to this one)
