Sims Running Everywhere?

[RubyLovesSims]

In a game of mine, I had a pair of twins, which I had no problems with until they became either children or teens, can't remember
They started to run everywhere! Instead of just walking to the fridge, or anywhere else, I mean. One was Athletic, but I can't remember any other Athletic sims running everywhere, and anyway, the other was a Couch Potato! I have never had this happen before, has anybody else? I did a search on the forum, but I couldn't find anything, but sorry if this has already been posted.
Thanks!

We call that the Run Around Bug.  It seems to be caused from playing tag.  Here's a thread with more information.  You can ask more questions there, if you like.
