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.
