When Era started selling houses I bought one, loaded up on furniture, and went on my way. A few months later I quit Era and went back to Classic (don't hassle me about it). Today I tried to log onto Era and the app wouldn't open. I have this problem with Classic occasionally as well, possibly because I am using an IPod Touch 2g. So I redownloaded Era, kept the stats on my gamecenter, and opened the app. All was fine, but the button to enter my house was gone : I tried to restore the purchase but it said I hadn't purchased anything. I feedbacked because I thought it might have been a bug. After about an hour I try to invite a friend to my house from their profile, AND IT WORKED. We ended up at my house but I was stuck on my roof. It seems I can only enter my house if I invite someone and they accept. I DO NOT HACK, HAVE ANY SORT OF UDID FAKER, OR A JAILBROKEN DEVICE.  

Yer, sometimes when I try to enter my house it doesn't work or I get stuck on the roof too. But I don't know about the button to your house being lost :O  

The only house I have is a gang house and I don't get stuck on the roof... I just step off. No lie.
