Oh wow, this is so the update I needed. I really have been voting every day, but for whatever reason, I didn't always get it inside the 26 hours. So never did increase my streak. I think now I'll stop loosing days.
I am confused on something. Every 20 votes we get a vault voucher, so if I voted for all of the servers each 20 times do i get a vault voucher for each one or just one vault voucher?
No. If you vote for 20 days you get the Vault Voucher. If you vote 20 times under 20 days, you get more rupees.
I understand that but i am at 16 votes each almost 20 for every server, will i get a vault voucher for each one I hit 20 votes on? I understand I need to vote 4 more days.
Not quite the best explanation of it. In order to get a vault voucher, you need a streak of 20. A streak of 20 does not mean 20 days, not any more. As the OP says, you may now increase your streak every 16 hours. Voting on a site of course increases your streak by 1, but voting on another does not increase your streak again, for at least 16 hours.
