[FIXED] Sim walks on knees

I noticed this with my sim's daughter. The mother lived in a different household.  I did not get a chance to play the other family before she came for a visit my male sim. Instead, I added her to a club, so that she visited fairly frequently.  I didn't notice her having a funny walk at that time.  She eventually changed to teen. 

I also made a later change to my "father" sim's lot, to put in "bracing breezes" lot trait, for my sim's workout club.  

It was shortly after that, when she arrived for a club gathering and I saw her crawling up and down the stairs like a toddler, and sinking into the floor with every other step. I tried to edit her in cas.fulleditmode but the behavior continued.  

I am going to try to take the "bracing breezes" off of my sim's lot and see if that'll cut down on the energized moodlet. It's awfully creepy to see them moving around with their arms and legs all bent up like that.
