I originally reported an issue against Extra Utilities but it appears some block within AbyssalCraft is the root of the issue. I troubleshot the issue by removing all mods but Extra Utilities and added them back one by one until it broke when I put AbyssalCraft back in.

rwtema's explanation of the problem is:

It appears some mod has added a BlockSlab that doesn't implement abstract methods. No idea how they managed to do this though since this should be caught in compile.

Note: In Single Player mode this doesn't happen. This only appears when starting up a stand-alone server.

Here's the server crash report

Alright, after looking through the slab files, I think I found the issue. For some reason, I was running the abstract method in the singleslab clientside only, which is wrong, as it should run on both sides.

The potential cause of the problem have been dealt with, this will be fixed when the next version is released.

Nice! Thanks a ton!

Huh... I thought I patched the slab issue in 1.6.0. I'll go through the slab code again and see if I can find the missing code.
