Hello again. As you can see, I am working on redesigning my house on Catskills. Just put the finishing touches on the decorations, when, to my dismay, I noticed that a few weeks ago when I enlarged a section by one tile space, I had neglected to add one row of floor tiles to the south edge of the room on the second floor. Now, this does not really show very much, but alas, is right next to the teleporter from floor one to floor two, and each time I move between floors I see it. It bothers me! My issue is - if I go into customization mode at this late stage, what will happen to all the bits and pieces I've so carefully raised using goza mats? Will all design areas done this way fall into a heap on the floor so that I'd have to redo everything? If so, I guess I can live with the missing tiles, but otherwise I would prefer to correct the mistake. I tried covering up the missing areas, but sadly all the patch attempts end up on floor one. Thanks again for your help here.
