Can't place rooms due to a fixed object in apartments

@crinrict I tried bulldozing and placing the apartments. This happened in a new save, on one of the previous ones I couldn't place VIII Landgraab top floor after the update. Before the update I could place the apartments I listed without a problem. I will try to include pics but all that happens is I place the blueprint within lines click accept and a red box shows up in the middle of the room saying can't place due to a fixed object
