Very Strange

[Scene23]

As much as I love this game. I've finally been able to get it together despite all the problems I have been having. However I know EA needs to give us a patch eventually, but can anyone give me some tips or something on this problem.

My sims don't do anything for themselves. Meaning: Like I threw a house party, and all the guests attended, but they all just stand around and do not even bother to communicate with each other. Even the NPC's in town, there were about a few of them at the bistro and all of them were just bopping their heads or yawning. One even pee'd on himself and still stood there.  {lol}

I have freewill on and as well as story progression, so it makes me believe that part in the game is corrupted. Anyone else has had this problem?
