The fix for the Public version worked for a few ingame days and then it reverted to the same issue: My 1 room apartment keeps changing from fully refurbished to low quality rooms in the pictures displayed when you are in those rooms, especially the hallway and living room. Buying renovations for them doesn't work. It takes the money from your account but nothing happens, no "under construction" status and no image change. The other rooms seem to work and display fine when you renovate them.
Same thing happens when buying a new apartment. The pictures shown in the real estate office don't correspond to the apartment you get. You choose a fully renovated one, buy it and when you go to it, the building staircase, apartment hallway and living room are different, showing other pictures from a fully rundown apartment. Kitchen and bathroom seem to be working fine.
