I'm not sure, Tliff should be able to say. But you can ignore this. The pictures are not even yet in the vault!

i tried moving shots from the temporary location to the contest
a highscore was generated for those, now since there are no shots in the contest no new highscores are generated and the old ones are "stuck"
and you are not supposed to see that anyway ;)

or

maybe the theme Chrisy's Favourite Shots

i lost a underwater shot

so we know now: it's about one-eyed women chewing bubblegum underwater. I'll go check my dvd's for that now.....

my shot is just a woman walking, whit beautiful colors mixed with animation... no bubbles, no water...

I lost a shot with only two colors (red and yellow). Without any real clue.

Think it's all about bright colors or contrast.

Or Chrisy just removed random other shots to gets us wondering... :P

Same here, my had a lot of the same color :) Cool!

And now I also figured out which of my shots has been moved! It's a red negative shot, so that would make sense with colors.

hmm i have now 16 solved and 1 upload

but after my name there is 15/60
and its now about 8 hours ago and it still didn't changed

I'm pretty sure its just the leaderboard not updating, so dont worry about it too much. If you can see your true solves in the overview I would assume thats all that matters. Im sure tliff / naut will get the leaderboard sorted but as long as you arent actually losing your solves its no biggy at the moment.
