Crashed while hitting a cow.

[Dogleader6]

Edit: Further testing, hitting an entity with any item that was from randomly generated ores seems to crash the game, not just cows. Normal materials work fine.

Edit 2: I was actually on 0.1.7 instead of 0.1.9, I'm testing the newer version.

I don't know what happened, but I hit a cow with a randomized sword and it crashed. OS: Windows (but I use macos bootcamp to run windows) crash report: ---- Minecraft Crash Report ---- // On the bright side, I bought you a teddy bear!

I'd like to also mention that this happens repeatedly, not just once. but only when I hit a cow, I'm testing on other animals.

[ValkWetenschap]

This happens to me as well, which really sucks because I love the idea of the mod. Does anyone know how to fix it? Does it happen with all versions of the mod, or just a couple?
