We tried starting a new game, and this actually worked for a while; although today, it is now freezing. In a private message I had with one of the moderators, they truly suggested re-installing the game software, which my son was opposed to doing; but, this is very likely the best option (even though it means some extra time, and not being able to play the game for a short time). But, in the long run, if it eliminates the problems, it is certainly worth it.

jk22 - what I found worked for a sim that was frozen (and everything else worked fine) was going into "Edit Town". Go to the option with the three dots on the main page, and on list there will be an option called "Edit Town". Then, when this opens, click on your active household. Then, if you select the option to split household, and put the sim who is "frozen" on the clipboard. What I did then, was select this person and place them (just for the time being) in a vacant lot or empty household. This way, their profile would not be deleted. I would then save and return to the game. Then I would re-enter "Edit Town" and select this sim, who I had placed in a different household, and select the "merge" option, and put them back into my active household. Then I would save and return to the game. It has worked every time (as I've had a sim with their foot stuck in the ground, and I've had a sim stuck in bed too ... and if you don't do anything, they will die or be taken away from you by a social worker - if they are a child). If it's a child who is stuck ... when you go into "edit town", you will have to place them with an adult, otherwise, you will not be able to place them anywhere. This also worked for my son, when one of his sims had a plate stuck to their hand.
If you need more explanation, let me know.

I was wondering; but does the game get "bugged" by the objects, lots, etc. that can be downloaded from the official Sims 3 website? Or is this caused by other problems? The reason I ask is because we have only downloaded things from the official website, and have not used MODS, etc.
Thanks.
