Load Error Code 800/801

I have this lot that is a residential rental and If i try to go into build mode it will either give me error code 800 or an infinite loading screen. I have tried to place down a blank lot but that just makes the manage worlds building load infinitely. I even took out for rent and i still can't access this lot. Is there anything else i can do to try to access this lot as it is the only thing corrupted in my save file. This happens with all mods and cc off too
