Hey there! Just wanted to note this specific issue also occurs on PC on several different servers. The build tiles load eventually, but at an extremely slow pace as if the streaming was somehow stalled.
Every build tile around you when you log in loads very swiftly, but if you enter a new area, it can take up to an hour for every piece of build and deco to load (doors usually take the longest to load, which of course is an issue since you can’t interact with them, to open them and enter).
It occurs modded or unmodded, as well as on servers with a low or a high concurrent pop.
The best way to make building tiles appear quickly is to log out, log back in, and it will immediately load everything… which is obviously problematic for a lot of reasons ^^’
