Minecraft Version: 1.7.10
BloodMagic Version: 1.3.0Beta-4
Forge Version: 1.7.10-10.13.2.1236-universal
Using version 11 of Bevo's Tech Pack, with some additional mods. I'm trying to manually update BM on my Single player Server. Upon attempt to launch I get the following crash. Removing BM or downgrading to version 1.2.1b seems to fix it.

Hmm, currently attempting to find the issue. So this is a server, meaning I'll have to find where the side-only stuff is failing.

Found the issue! Please download -5 http://minecraft.curseforge.com/mc-mods/224791-blood-magic/files/2221691 for some corrected code :3
