The Minecraft client doesn't crash, but the server stops responding and repeatedly reports a NullPointerException in WayofTime.bloodmagic.livingArmour.LivingArmour.hasFullSet (LivingArmour.java:245).

I'm using BloodMagic-1.8.9-2.0.0-10.jar from curseforge.

Here's the log:

I am having this same problem and can add that punching an entity (in my case a Cow) crashed the game 3 times in a row.

Crash report is here: http://pastebin.com/vj2hShRU

(Edit) Hmm I don't know why that link didn't work but copy pasting it in chrome works.

Sorry for the bug, folks! Since it is a major enough bug, it is being pushed to -11 right now. Thanks for your patience!

sigh I forgot to null-check
