puzzles expired too soon

675 expired hours before the time written on the puzzle page.

still has 5 hours to the end of puzzle 675 and cannot be played…

I noticed that puzzle 673 expired more than 5 hours before it was scheduled to. I improved my rank during that time but it didn't show up on My Page. I hope that this bug can be fixed.

I don't know why this happened, but I have re-opened it and added 5 hours to the closing time.
Please let us know if this happens again!
Hopefully we can find what went wrong!

It is still not possible to open that puzzle in a (new) client.

[Timo van der Laan]

In fact I think it has closed again!

[beta_helix]

Yes, it keeps closing at the top of every hour (despite the fact that I keep re-opening it).

We're trying to find the problem, but sadly this is happening on the Sunday of a 3-day holiday weekend :-(

Thanks for your patience… for now I will try to keep it open as much as possible with the target closing time of: 02/18/13 05:00:00 GMT

[Timo van der Laan]

And now the same thing is happening to 674, 8 hours before closing time. Maybe it is a timezone issue.

[beta_helix]

We think we've solved the problem… please re-open this if it happens again.
Thanks to Timo van der Laan for the tip as to what was causing this!
