Describe the bug
Several inventory pets do nothing at all. No config is changed, so the ones who are supposed to be enabled (I.E. Sheep pet) do not eat and are not able to be activated. Maximum stage progression achieved in case some were simply unlocked later, still cannot activate. No inventory pet passive activates, nor any activating power when right clicking. For some reason, the eating noise plays once in a while and still does nothing. Crafting a Feed Bag does not fix the issue, nor does crafting the mod specific nugget that a pet needs. A pet with a Shift-Right-Click ability will display its correct message above the hotbar, but does nothing afterwards.

To Reproduce
Steps to reproduce the behavior:

1. Obtain any non disabled inventory pet.
2. It does nothing, does not eat, does not activate abilities.

Expected behavior
The inventory pet should automatically eat its favorite food from your inventory if it is in your hotbar. Then, a bar would appear showing its hunger lever and would decrease when you use its active or passive ability, which would then give you the ability.
