Following the hotfix, I cannot interact using left trigger with any animals tamed prior to the the hotfix. Dogs cannot be ordered to sit or to follow, and a tamed cat turned magenta. These animals cannot be fed either. However, newly tamed animals seem to be working as normal.
Moreover, farm animals (such as sheep, cows, etc.) in pens are affected. Cows can still be milked, and sheep sheered, but they cannot be fed. Chickens cannot be fed and are not producing eggs.

This does not seem to be the same issue, as it also affects animals in pens. Saddles disappeared off of horses. The effects seem to be far more extensive than issues with tamed pets.

I also double checked and insured that there is an operator listed, which is my Microsoft account.

Could you provide a video or world save showing the problem?
