It could've also been that there were buy orders for 0.006, 0.005, 0.004, 0.003, and 0.002.
And then someone decided to sell his coins, and set the rate to 0.002. Buggy mintpal then proceeded to sell the coins actually at 0.002, leaving the 0.006 - 0.003 bids intact.
And yes, that happened to me there earlier today when I dumped my shitcoin collection I had there. Exactly the same shitty functionality that the infamous cryptorush had.
I just tried to test that. Placed a sell order for 10 Blackcoin at a factor of 10 less than the current price. It just choked on it. There was a brief message saying "Attempting to place order..." and then nothing.
Then I tried another one at market rate - again, it didn't work. It wouldn't even place the order.
Other stuff doesn't work that used to - like when you click on a price in the order book it would use that price in your order preparation form.
