Moving Crash!

Hi there I currently downloaded ambitions and decided to move from sunset valley to twinbrooke, everything is fine til i actually move my sims into the house then the game seems to crash but the trees still move, I just cant click on anything and time stops, I heard there are some glitches with moving so I was wondering if it was just that? I've also uninstalled all of the expansion packs and installed them again ad still get the same problem, it's not too much of a problem but help is appreciated:)
