As I was building my 5th quest entry, I decided to make a "shop" room in one of my dungeons where you have to either buy a dummy rupee item (which costs 20 rupees to buy) or "buy" a free item that automatically jinxes you before you move on. The buying works fine but lets take a look at the prices...
As you can see here, the price for the dummy rupee item is displayed in the center and not directly below the rupee item as it is supposed to be.
