You know,there is a glitch in the OFB and Seasons expansion packs(I own both).The door is stuck,and,I know why ( I had placed a chair in front of it even without using moveobjects).If it would be a regular lot,there wouldn't be any problem,I could have solved the issue,but it happened on a apartment lot( as mentioned above).Please HELP!1!!

Have you tried the aptBaseLotSpecificToolsDisabled or aptSubLotSpecificToolsDisabled cheat?

If the apartment building is occupied, try the sublot cheat. If the apartment building is empty, try the baselot cheat.

You could also try the apartmentBuildBuyRestrictions cheat (same link as above).
