I cannot have these two mods installed simultaneously unless I turn off the Wolf Feature off in config. The issue stems from not being able to render the fluffy tail but when I disable that specific feature in config, the game still crashes for the same reason.

I've also submitted this on the WolfArmor issue tracker.

Completely disabling wolf animations is the only solution.

It's no very hard to make both mods compatible, but I don't have the time to implement this feature in the foreseeable future.

1.12 is now unsupported unfortunately.
