When a player tames a Ferret or Red Panda the entity is no longer breedable as they are forced to sit instead of passing the interaction. I have managed to fix Ferrets in a fork that I am yet to publish and I will likely make a pull request regarding that same goes for Red Pandas which I am currently working on fixing.

There is also another issue related to this that I have worked around but not exactly fixed:

this.goalSelector.addGoal(5, new FollowParentGoal(this, 1.0D));

This line in the code for both Ferrets and Red Pandas breaks the owner follow code for baby variants. Its hilarious however ultimately a bug. The baby entity will stay in a sitting position however if the parent moves or follows the player due to this Goal the baby will follow the parent scooting around sitting down with no animation playing. I have had a look for examples of having both FollowOwnerGoal and FollowParentGoal however in the base game and other mods FollowParentGoal seems to be omitted from tamable entity's. So that is what I have done in my fork.

Question has there been an offical fix for this?

Thanks for the bug reports. Everything should be fixed in version 2.0.2.
The baby_red_panda.animation file was missing a sitting animation, making it look like the panda never sat down.
It's important to note that the FollowParentGoal had nothing to do with this issues, as its behavior is superseded by SitWhenOrderedGoal, which holds a higher priority and the same Goal flags.
