The trade was cancelled. Your key should have not been sent.
I think the problem is that the buyer's trade was created when Bitcoin was at a higher price and the same amount of Bitcoin could not buy 362 keys anymore.
Yeah. Sorry, I could've edited this, because I worked out where my confusion came from.
There seems to be a timeout triggered when listing a large amount of keys, which threw me off and also the cancelled icon isn't displaying so I didn't notice that the trade didn't complete. Both minor issues, but I thought you'd like to be aware of them anyway.
