Losing during a Possession causes the game to reopen/freeze.

I don't have the game number, as I refreshed the page before it occurred to me to report the bug, sorry.

If you possess somebody (or at least the bot, I haven't played a human here yet) and lose the game immediately afterward, after you get the result screen and press Ready, the previous game will reopen, show you the other player's last turn, and leave you stuck on the game screen unable to play. Pressing Resign brings up the confirmation dialog, but confirming does nothing.
