Description of the Bug: Cant buy Bazaar when you have Market Stall. Its saying something like "Your org can only own of Bazaar". Cant remember exactly, since it happened yesterday.
How to reproduce the Bug: Have a Market Stall and try to buy a Bazaar Shop
No you can have one of each type but they are not purchaseable in every order.
You can buy a bazaar first and then a business or stall.
But if you own the stall first for example, it wont let you buy a bazaar.
