Visitors Will Not Come into My Apartment

I "locked" my apartment doors because the Landlord kept using my trash compactor to throw anyway his trash. But then when I called up a Sim Friend & invited him over I "unlocked" the door - & no matter what I did - "Call Sim Over" "Ask Sim to Join" he would not come into the apartment. It is totally annoying. I thought for a moment that by having "locked" the doors once I had to let a sims day pass before the invited sim would know the door was unlocked & then would come in - NOPE. I thought if a left the sims family & came back to play them again the game would read the "unlocked" doors & the invited sim would come in - NOPE. Now that I have unlocked my doors the Landlord is using my trash compactor again & the next door neighboor (who HATES my sim & even had a fight with the him & beat him up) comes inside to dance to my stero - but will my friend sim who I invited over come in to watch TV - NOPE. I finally used the "moveObects on" cheat & picked the sim up and put him in my apartment. Now will he be able to leave on his own or will I have to pick him up & put him on the curb to say goodbye? Has this happened to anyone else? Any suggestions? It is so annoying. I have read other threads where people have said they do not believe the EA programmers actually test the games before they put them on sale. I never believed that - but now I have to say they may be right. I mean the landlord using my kitchen is silly & a neighboor sim - who HATES your sim - just walking in & dancing in your living room is just stupid.
