This is the third senate reset I have noticed this, but up until now I wasn't sure if I had mis-clicked.
I have tried voting for myself for team senate, which I believe should be possible, and the vote seems to have gone through as it won't let me vote again.
However, I received no vote as I still have 0 votes, not 1 vote.
Pretty sure this is a bug, I was able to vote for myself under the old voting system, and I was able to vote for other people under this voting system just fine.
