Not likely. Several people have stated they had sells at around $10 that didn't get filled. Looks a lot like a bug, or else the whole exchange has been compromised.
some people may be scared by the rally and attempting to spread FUD about orders not being filled, I personaly have no idea
If you think something went wrong you should wait for an official statement,
I'm just going to keep watching the market for now, If another decline stops at 4's instead of the 2-3 range I will probably buy back in. It's possible some people just bought because of a similar reason, the chance for the crash to 2-3 was right there and it didn't happen.
