Oasis Springs world messed up and sim at home but not!?!

Hi,I have a problem with Oasis springs and my household,Most of the lots from Willow creek just appear somewhere different each time I play in this one household some of the houses are sometimes even inside the rocks and there are sims walking everywhere in the water,ontop of houses and in the middle of the road.My household says the Child is at home caring for herself but when my 2 sims get home shes nowhere to be found reset sim wont work it says ''Sim cant be found'' something along those lines,this is starting to annoy me.It only started after using cas.fulleditmode,I guess thats what I get for cheating.I have taken pics if you dont understand. I have CC installed.
