When you used to put up buy offers in the Market, and you clicked the up button to make an offer for 2+ offers of 100 energy, the "post" button will go grey when you don't have enough crowns to back up your offer.
Now this doesn't happen anymore. When you put up too many offers, you simply press it and nothing happens.
This was a great feature I hope it wasn't removed intentionally. >:
if you checked the bug report section of the forum you'd know that this has already been pointed out.
