I saw someone else with this issue post a few days ago, so this must be an actual bug. That's pretty bad. It's gotta be worse for MagicalTux, though, since he'll have to pour through a lot of logs to resolve this.
My home network has a linux router and is ntp sync'd.
I can narrow this down to a half hour window and possibly tighter by looking at some other logs, so if I ever hear from anyone, I can hopefully make that log searching easier.
My original e-mail, with more details like account name hit Google's SMTP server for MtGox at Jun 8 07:26:18 (UTC -5).
I still think this was a server load issue and that it can be clarified, it's just disturbing that it has taken this long and that I've not seen others with similar issues.
The closest thing I can think of is where I registered (with some other service, not Mt. Gox) two usernames without realizing it. Logged in as the wrong one and saw no activity.
The account is a few weeks old. I am certain this is not the issue.
I placed an order and I sent 10.5 btc in.
The way you wrote it confused me. Just to make sure I follow,
You had a balance after adding Dwolla and using that balance placed a buy order which got a partial fill.
You then, coincidentally, did an Add Funds -> Add Bitcoins entered 10.5 and then clicked Send Bitcoins. Then you sent 10.5 BTC to the address that you got from Mt. Gox: 1PsAZgtbsYLEqo7k1gxakyyYgRRhUoSrDS
That is correct.
