I am getting this "not enough coins" screen frequently.
My account has 2.8 bilion coins in the marketplace display or negative 1.3 billion in the main display.
Has anyone else seen this screen.
I have tried buying Treasure Terraces & selling them to reduce my
coin collection but this screen still pop up frequently.
I need to exit DS & login again to be able to play "normally" until this bug reappears.

The bug appears when you do something that require coins.
The displays shows:
NOT ENOUGH COINS!
You need 1,115,551,360 coins.
Would you like to buy 10,000,000 coins for 500 golds?
