Just use pastebin or google docs to post the fixed code if its against the rules.
Ive also only noticed it with baby animals, its their hitbox being different isnt it?
It also seems to happen with there being too many animals in one place, is there something in the code that makes them try and spread out?
Im getting this too, more like 300 chunk updates though. And its only on the server.
No problem prior to 1.7.4
