What gameplay feature is this bug affecting?
GB Sales

What's the issue? Please include any error messages you receive and as much detail as possible.
When I try to purchase this 100SB GB I get the error "You can't buy this GB."

This is despite the fact I clearly have more than enough SB to buy this GB with. There's no explanation as to why I cannot buy the GB, so if this is not a bug, the UI is not making it known why the acquisition is not possible, which is a must in any UX.

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?


Any screenshots you can provide us with?
