I have added a series of questions like Group winner to my pool. First 5 questions closed on time specified in 'anser before' but later question do not.
I've tried setting the clock back (i.e. closure time is 2014/06/16 00:00 and I've set it back to 2014/06/15 22:00) and it didn't help.
Please check it out as it makes cheating possible in the competition.
