game loop

since the last small update my game has played for maybe a half an hour then at a point started looping the same animation.  I believe the game is frozen as time stops but everything happening in the game continues on.  the first time it happened a sim had gone to the restroom and all the people surrounding her kept on.  I keep all walls down to see what's going on.  Time stopped and I couldn't switch sims or make them move.  The sim just stood there.  Today, I had a sim dumpster diving and the animation to dive in and come up repeated on loop with no item found notification.  Time stopped and the baby goat next to her slept on with the ZZZs floating overhead as if the game was playing fine but the sim was stuck in the loop and time wouldn't pass.  I could not save when exiting so all progress was lost.  Attempting to save forced me to shut down my computer to leave the game at all.  

Though I don't think this is related, my sim also cannot adopt.  They can select it from the phone.  Choose to adopt a child, and then the the whole thing stops with no adoption list propagating.  This has been the case since the expansion to prepare the game for the new expansion pack.  If you wonder why many of us are not getting the pack, why would we get more content when what we have doesn't work?  I love playing sims.  I'm a writer and use CAS to crest characters  when I can't get a sense of what they look like.  I use Build and buy mode to get a sense of spaces because I have a poor sense of dimension, but this sort of thing makes the game unplayable.
