Just had a crash ("Description: Rendering entity in world") after breeding two cows together with wheat. Had bred cows earlier with no issue, but this may have been the first one that was a Quark type? Can't remember exactly. Full details below.

Quark Version: Quark-r2.1-213
ARL: AutoRegLib-1.5-36
Forge: 31.1.18

FWIW, I was unable to reproduce this crash in a new world. Produced dozens of baby cows in Creative, both through feeding adults wheat and through directly producing them with the spawn egg, but no crash.
