Error code still occuring

Flower01373  Ok, if you deleted the ladders and are still getting the error message when you try to enter the lot, there is one other thing you can try.  Judging from the LE, the game is seeing a ladder on the lot and not finding it.  My guess is during building the lot, you deleted a ladder at some point that the game thinks is still there i.e. invisible to the eye.  So, move the sims out.  Go to build mode from the map, save the lot to your Library, bulldoze the lot then replace it with the copy from your Library.    That usually clears issues like you're having.  If you can't enter the lot in build though, then you might have to replace the lot directly from the map screen if you already have a copy of the lot in your Library.  Doing it that way when the lot has an error may take a long time.  So, be patient and let it go on for at least 30 minutes or more.  If it doesn't finish before then; the game has run into a problem and has gone into an endless bulldozing screen which you will have to force quit.  If you can't replace the lot, that lot will not be usable anymore.  At that point, you might want to consider making a new save via New Game.

Hope this helps.
