The same kind of visual glitch happens at the "Miner Mansion" lot (where the Harris family lives) in the Grims Quarry neighborhood in Evergreen Harbor.
But the visual glitch only happens when you go to Build Mode straight from Manage Worlds.
It's fine in Live Mode, and when I tried going to Build Mode from Live Mode.
(This is after the 1.117.244.1020 patch for PC on 4 September 2025.)
Exactly the same has happened to me. Entered into 'Rockridge Springs' from manage worlds and all debug/world assets are missing. Go into LIVE mode and travel to the lot with my sim and it is all back to normal. Go into Build mode with my sim visiting the lot and its all fine. PC, current patch, DX11.
