One person joined our lobby. We were about a minute or 2 into the first round. So I that aborted the game so they could join in, since we had only just started. When we then started the game the person got to the screen attatched. And got an error message when trying to rejoin. They could still chat with us from the lobby, but not rejoin the game. They couldn't even join in as a spectator.

We then aborted again and tried shifting the person from one team to the other. Both by the host switching them around and also the person themself switching team. Started again. Didn't work.

We aborted the game to then try and see if the player could just leave the lobby from the exit button and rejoin with the link again. That didn't work either.

So we closed that party and started another and the issue didn't appear again.
