[ARCHIVED] Orange/Green Exclamation signs over lots / Houses disappear

@LauratkoK the gallery is a mess, and has many issues of its own, I might be wrong but I believe the fact you might download a corrupted lot is one of them - and there's no way to know which are corrupt..... again something else we can't rely on to be safe for our saves.

My long term save gave me these exclamation marks after For Rent, and after I had both downloaded from the gallery, and also converted various in game buildings to residential rentals.
