Describe the bug
Gorgons and cockatrices are having a fight and it makes the game crash :(
Also using the gorgon head on a cockatrice also crashes

To Reproduce
Steps to reproduce the behavior:

1. Spawn gorgons and cockatrices
2. Alternatively try to turn a cockatrice into stone using gorgon head
3. It also seemed to crash whenever cockatrices attacked things (even things unrelated to gorgons) although this only happened in my survival world with a lot of other mods.

Versions (Note that 'latest' is NOT a valid version!
Chocolate Quest Repoured: 2.6.2B
Forge: 14.23.5.2860
Minecraft: 1.12.2
Other mods (necessary to reproduce the bug): Ice and Fire

So I was bored and decided to experiment. I managed to fix it by deleting the files (com/github/alexthe666/iceandfire/entity) related to ice and fire because I guess stuff hasn't been fully implemented for that

First: Do not ever delete ANY class file from ANY compiled jar, that is stupid and will cause issues

Second: Just fixed it, it was a typo. Your "fix" did work because i&f was installed, it will directly crash if you remove i&f from the installation.

Patch fiwll be published in the next update
