I had no problems yesterday, but today I see 2:
1. Despite picking all the right answers (and getting green for all of them - you don't even need clues for them right now, so easy!) I didn't get on the list of winners and (obviously) didn't get the prize.
2. After page refreshes to leaderboards (and a countdown to next quiz) - number of winners and prize amount is different form what quiz result did show after completion.
And if you check the full list of winners - 3 users on it with 0 points: ChaosReigns, Rasmus, and Anthony Pearce. Just a visual glitch or...?
P.S. Actually, make it 3: amount of points in my "personal" strip is different from top100 leaderboard - 10010 against 10530. And "personal" shows points for last quiz: 550. Amount of credits still the same as was yesterday. Something somewhere doesn't update correctly...
