This is probaly already known but I couldn't find it while reading through the cheat
For the cheat "Moveobjects On/Off", when this is active it is also possible to not only move objects but Sims aswell, both playable and NPCs at your property. I use this alot when my sims get stuck or if I want to move a small child or puppy/kitten up and down stairs. I am not sure if this helps when a sim freezes, as I didn't check this when my foal once froze and just stood there. It is very possible you may have to reset a Sim if it get frozen, but for pets it will do the same by simply adopting it away - you can adopt it back the second the animal and car is out of sight. This way you keep all the points, memories and friendship with the animal when it comes back
Be aware when moving sims with the Moveobjects cheat though, as you move them in build mode you may accidently delete them! But this might be wanted with that annoying maid or sibling you don't want in the neighborhood anymore, without all the hassle of killing them
