when used with quark, even when all quark features are off, the following animal models stop working:

cow
pig
dolphin
chicken

everything else works fine, it's just these few that are not working. when quark is off, they work fine. when quark is on, but all features are off in quark's config menu, they do not.

mod ver: 1.19-5.6.0
Minecraft ver: 1.19.2

same issue, will this ever be addressed?

Same issue here;

I have this issue as well. At first I thought it might be a resource pack taking priority somehow, but i have quark as well so it's probably the same issue.
