Crash when trying to attach lead to cow

[DaedalusProspect]

Hey guys,

Currently hitting a crash whenever I or anyone else on my server tries to attach a lead to a cow. This crash is client side only, and doesnt affect the server at all.

Tried removing battlegear as well and the issue persists until Project Zulu is removed. When you load back up the client, sometimes the lead will then be attached to the cow.

kcauldron 1492.152
Minecraft version 1.7.10

Thank you for reporting this. I'm planning on getting back to MC modding soon. I'll check on this as soon as I can.

[DaedalusProspect]

As an update, the bug seems to extend to interacting with cows. As if you try to feed them wheat, you get the same error as above.

But good to hear, I appreciate the support. It's nothing major on our server so were not in a rush for a fix. Thanks!
