Hi, Patrick.
I have sent the solution for today's 12x12 but the main page does not show in green the corresponding label in the upper line (this happens any time I reload the main page for the 12x12), however I always receive the proper msg "Note that you've already solved this puzzle". My history shows the 16 points and the golden star is also shown, however it seems that the 16 points have not been added to the accounts (Last 7 Days, Last 30 Days and All Time) nor in the upper counters in the page (at the moment of finishing the puzzle the msg "Submitting your solution ..." appeared in the screen but like in a "frozen" condition.
I have the printout with this solution but since the 72 hours are running I cann't sent it here.
