I've noticed just the opposite actually, my cats seem to frolic and play more since the update as long as the ball doesn't sink into the floor of the house. Don't know, might be region based? I have a linden home in Nugu I think it is and land with Belle Pointe. Not sure what to tell ya but I'm sure they are hard at work to fix it, yet another example of how KC is once again superior to LL in their service and commitment to solving issues of the customer.
Thank you KC Team and Happy Birthday again !!!
