Please use this thread going forward: Neighboring Houses show as Default/Empty | EA Forums - 11903590
I have this same problem in more than one of my save files, but without the endless loading screens. One lot (the saloon in Chestnut Ridge) even appeared as being bulldozed rather than the EA default, but when I traveled to the lot it was there as it should be. Some of the lots with this problem were downloaded from the gallery while others were lots I built myself, but in all cases they did not have this glitch prior to the most recent update and used to show up normally.
I assume you mean from map view, like the "incomplete lot" warning symbol? I don't have any exclamation marks on any lots as far as I can see, and all lots also appear as the correct version from neighborhood map view. I have noticed that in the save files where this bug happens, every single lot in every neighborhood will show as either EA defaults or bulldozed if it isn't the active lot (only the one lot in Chestnut Ridge has been "bulldozed" so far, everything else is just the EA default) from both live and build mode, so it appears to be a glitch affecting the entire world and not just certain lots.
