I see multiple people have gotten a similar bug, but yes; after restarting my game due to audio issues, I tried to rejoin but the game was already finished. All the playable characters had been clumped together (as if being dragged to their own spawn), only the ominous game victory/defeat ambiance was playing. Others managed to join aswell.
