You can try the following:
* Enter the following cheat: BOOLPROP APTSUBLOTSPECIFICTOOLS DISABLED FALSE (remove the objects)
* Enter the cheat BOOLPROP APTSUBLOTSPECIFICTOOLS DISABLED TRUE (after you have removed the objects)
****A WORD OF CAUTION: This is not a cheat that should be used arbitrarily. I've used it to place cars on Apartment Lots (a long time ago); I've was cautioned against making a habit of using it for that purpose. However, this seems like an emergency situation. Now in regard to the caps I really don't remember if they are necessary - this is how the information was saved. I found the cheat several years back at Sims2Cri.
I hope this helps - in the event that it does, I'd make a habit of backing up your game after each game play just in case you run into problems again. I would also make sure that your game is properly patched as your specific problem sounds like something that was fixed in the AL patch.
