I don't see anyone else having mentioned this but the Mega Race seemed to have ended and awarded prizes at 10am (or at least before 11am, which is when I logged in and saw it) instead of 10pm. It already had the "Mir wins congrats" message then, and now, after 10pm, I see no awards for having participated in it.

I was slow awarding prizes, you should have your prize now.

Ah, I see, thank you and sorry for my impatience. And thank you twice for such a nice piece of tack for the surprise :)
