Bugged "Pamper on Couch" Interaction (Pets Expansion Pack)

Not sure if this happened to anyone, but just now, I tried pampering the pets in my household and it glitched. What happened:

- Most, if not all of the interaction, there was no animation trigger. All they did was acknowledge each other from time to time with their head positions, but they remained stiff as a statue.

- Both pets were in different comforts (a couch and a loveseat) that were next, but not connected to each other. When the sim in question tried to interact, he glitched from one seat to another.

Hopefully it was a one time occurence, but I'll remain vigilant if it happens again.
