When I check the science puzzles, it shows an empty screen.

Puzzles 193 does show up on the expired list (without score and ranking), but it shouldn't expire today...

I entered the puzzle using the continue button, but the game itself doesn't show the group or player scores.

I'm sure you'll get this all fixed soon. In the mean time I wonder if it makes any sense to continue working on this puzzle? (Oh...and who threw their cup of coffee over the server?! :P )
