I can't remember exactly which game it was in (it was ages ago) but we were playing a 2v2 and one player on the other team was on vacation. The autoboot was 3 days, but as the other player was on vacation the turn had gone over 4 days. My team-mate then realised he had made a mistake with his move, and clicked the re-do button, and subsequently got booted straight away before he had time to realise what he had done.
I think that it should either be made impossible to re-do your turn after autoboot for you has already passed, or there should at least be a message telling you what is about to happen.
This is just luck or unluck. In that moment, likely server check games when your teammate uncommit. Very unluvky. Is never happen to me (and i did it many time).
