@missladycartier I would try make sure the lot is unowned, then enter the lot and bulldoze the lot and then the terrain, save the game at that point, then leave the game and remove the following cache (the one you already removed plus others as directed at the link below, and then see if the same result is there:
How to delete cache:
• Exit your game and Origin
• Go to Documents > Electronic Arts > The Sims 4
• Delete the localthumbcache.package file in your “The Sims 4” folder (your game will re-create this folder next time you open the game)
Directions on how to delete additional cache if needed:

If after all of this the save still shows the odd image in worldview but the lot is still functioning normally, I would assume the lot's bugged in that save. You could then choose to either play it as-is (if that visual glitch in worldview is the only issue and the lot plays normally) and hope that it eventually works itself out...
or...
Move your played households from that game save into your library taking note of their current funds and moving all Sims that you want to maintain relationships with into the same household (in the library all relationships outside of those in the saved household get severed, as does their personal inventory... if you want to save any items in their personal inventory you can first move them into a room or the home and save it into the library, but be aware that there are a small number of personal items that don't save to the library). You can also save to the library any lots in that save that you want to keep as-is. Then start a new game save and place the saved lots and households from your library. Then you can split the households into whatever separated households you want, and cheat back their previous funds and real estate. If that all works out, you can abandon/delete the save with the bugged lot.
