You must have been off from the voting window, maybe it was before the 22 hrs, I see anohter one that was missed too, the problem now is if I got back and manually vote anything. it will reset your time from that vote, so I'll miss you next one as well. It's not really a perfect system for missed votes, but's here a trick, if you noticed your posts was skipped, try to edit it and repost and it will trigger her to look at it and vote. it should keep you mostly on schedule.
Based on your previous posts I suspect you are going to vote soon, if I catch it i'll try to catch up, otherwise in the future try to edit thing, since it's a huge headache to catch up, sorry dude.
