Seriously, Mt.Gox ?!

I see the price in EUR falling to the 630s, my order gets processed, price goes down to 625.12 EUR.
Then Mt.Gox rolls back the trades and we're back at 660 EUR and my trade(s) never happened. Saw it happen 3 times already.
I have NO idea how many BTC and how much fiat I have right now. And even after 30 minutes, some orders are still "Pending". Not cool.

PS: It just happened again. Down to 625.12 EUR, then back to 660.00 EUR. #MtGoxLoop
The trade @ 631.24 is mine.
