I want to know if when you customize you house is there any limit on to how high you can build it? I mean looking over to the right side of the customization bar you see 3 levels and a roof. right?? Well i built what I thought was my dream home last night which by the way only took me around 3 hrs (first time building one with a roof) and when i tried to save it and convert it it told me that the house was illegal??? So I thought I might have left some of the old house there and there wasn't of course.... But It still would not let me commit the house.. So I started all over again and this time after about 2 hrs the same thing??? So my question is will I have to buy the extra house storage in order to build a house with 3 story's and a roof? Or is it something else?? Any one have any clues??
