Building plot cost after gold acquisition

31/01/16 14:06
The money cost to unlock building plots is unrealistic if you've unlocked the majority with gold. The price of the final slot in my city is 270,000,000!
This is more than the capacity of all banks fully upgraded.
Can the value be reduced to a realistic amount?

No response to this yet from support. I'm not there yet but would like to know how it gets resolved
