last player on red goes spectator when match end about haxball_bot_headless

It is linked with these lines in the balanceTeams function:

if (streak == 0 && gameState == State.STOP) {
    if (Math.abs(teamRed.length - teamBlue.length) == 2) {
        var teamIn = teamRed.length > teamBlue.length ? teamRed : teamBlue;
        room.setPlayerTeam(teamIn[teamIn.length - 1].id, Team.SPECTATORS)
    }
}

This is supposed to rebalance teams if both captains are choosing (streak == 0 is only supposed to happen if there was a draw). But in your case it wasn't a draw, so what happened ?
I have seemingly forgotten to update the streak correctly, so this is a very important bug you spotted, and I will fix this in the same update as the issue before, in the afternoon.
Thanks for noticing as always

For the other problem, I'm not sure at the moment, but fixing the first bug might be a good first step
