buying a casino is impossible
I go to different real estate offices and they all say the zone is full but there is no link to go to a different one like there was when I first started playing the game. Also, it won't take a bid on the auction table either.
I'm about ready to just quit because by the time you fix this, I won't have enough CP to get a casino property anyways.

The button only shows for your first casino, but we’ll reevaluate if it should always show instead. One thing we aded recently to make this easier is that you can scroll around on the expanded mini-map and see available lots marked in red/white. If you click on it you can then go directly to the related real estate office to buy the lot. Can you give some more details about the auction? Are you getting an error message?
