Thank you...everyone.. Next time I play I will see if this happens again and try to get the info.

I'm sorry, I don't know much about computers.  I don't know what an objects error is. If it has anything to do with Simpe...guess I am in  trouble because I have never used it. Also I don't know how to add attachments. So never mind I guess...just thought there might be a fix for this.Thanks anyway.

I notice that when I sent my students to college there seems to be a sort of jump bug when they do group research together. They seem to all take turns jerking !! It is really werid. Everything else seems okay. Anyone else have this? Thanks 

I have done something like...used the teleporter to take them to another house and let them call home...but now that house is corrupted too because they cant move out from there! I am afraid the whole neighbor is going.! 

I have a big problem..I have 2 corrupted dorms...the sims after graduating cannot not move out! I tried to nuke them with the lot debugger...it doesnt help..I installed the new patch ...and it didnt help ..I  really dont know what to do..(I hope I dont have to reinstall my game.) Any suggestions?
