Hi, i downloaded the full $13.00 Interior Design app on my ipad about 9months ago and i have been having trouble with it ever since when i build houses/buildings i always get this Weird grey stuff on my walls which i cant get rid of, if i put a door in or a window it doesn't function as it should. And sometimes my whole doors disappear Image attached below. You can see the grey walls, i am also getting grew parts on my floor too it almost looks like a huge hole!! which is REALLY ANNOYING. Also maybe you should update this app i LOVE this app and i am very addicted its great awesome graphics, id just recommend more furniture, better out door plants, stairs that matched upstairs and down stairs, a roof on the house! And accessories for the house out door and in door.
Thank you i look forward to hearing back.
