Witch's Cauldron causing crashes

[talpidae]

Minecraft version: 1.7.10

Unabridged version: R13a (yes, installed update rolled out yesterday)

Issue Description: Dedicated server is kicking players who are standing or running near a Witch's Cauldron Players are unable to join again, they get kicked immediately. Tried to remove it ingame, got kicked too. Will it work, if i remove the Witchery Mod as a temporary fix?

Steps to Reproduce: Just place a Witch's Cauldron

instead of putting "Latest from AT launcher" please consider putting the actual version: Unabridged R13a
