I've had the same problem with the sim freezing and time continuing to run.
Example 1: I send my sim to a new lot and have them do something (like go here) and the action bubble will not drop to the bottom of the action queue. So, I pause the game, and it eventually will drop down (this take a few real time minutes) when it does I un-pause and they go right to it.
Example 2: I try to make my sim do something and the action bubble does drop down to the queue, but they just stand there (I've seen times where it's 10 or so sim minutes or more). In this case I just pause and un-pause right away and they go to it. For example, my sim picks up her cat to hug (action drops immediately down to the action queue, she picks it up but just stands there with the cat in her arms. I pause and un-pause and she hugs it. Then the put down cat comes up and she just stand there holding the cat, pause - un-pause she puts it down. Very annoying but it works to keep going on.
I'm playing the PC version, and I have everything they have released for this game.
