I am trying to customize a house for a friend. I have been super careful to not have any orange tiles and to make it structurally sound. Every time I try to commit the design it says it isn't structurally sound and to get rid of orange tiles. The first 20 times that I tried to commit last night. I had to keep deleting the roof items that I put on the first floor. They would NOT delete. I would delete go to another floor, look down and there they would be again. I did it a million times, so frustrated. I finally went to blank state on the house and started it up again. So, today I again redid the house, put a few roof stuff on the fourth floor, went to the first floor, came back up to the fourth and it deleted the roof. I am pretty sure it's the roofing or this spot is just all kinds of bugged out. The sign says house is placed properly. This reallly sucks. I just want to commit the fraking design. Anyone know?? Yes, we placed a ticket, they said to report it as a bug.
