Not to necro, this, but, we still seem to be having issues with the vote reminder.

For the last 2 days, for me, I have been getting the reminders even after voting. I get them when vote sites 1-3 reset, so I go vote, but 5-6 are still on timer. I will still get the vote reminders after voting on the first three sites, and still get them even after having voted on all six.

It's getting a bit annoying, to be honest.
