@11IDDid you try to do it after deleting the park and leveling the lot?
Have you any mods in the game?
This should change without a problem. Only special lots in Windenburg do not have this change option.
For now, if you have any mods move the mods folder to the desktop. Delete localthumbcache.package file in the game folder and fix the game in Origin.
Origin/Library -right click on TS4 - option "Repair game"
You have to wait until Origin will fix all packs, not only the base game.
If you don't have CC or mods delete this file and fix the game also. The game will create the same new file but without saved errors.
Turn on the game to create a new, empty mods folder. Check if a game is working now without mods. Then copy from desktop your mods and CC and paste it in the new mods folder. First, paste script mods every time checking if the game is OK. Do the same do the same with CC but if you have a lot of this, try the 50/50 method
If it does not work then we'll try another method later
