Steps to Reproduce:
The log is attached. I cannot describe the error that precisely. It seems to happen in relation with the mod 'Ice and Fire'. When the entities with a Gorgon head are turned to stone.

When the error occurs, it is no longer possible to continue playing.

Description of issue:
Game crashes completly.

This is a problem on ice and fire's side. The "entity" that's passed into the rendering for me to work with is not whats normally to be expected, to put it simply. I work with Minecraft's normal procedures, ice and fire makes that common procedure weird.
