Frenzy Push ball carrier KO

hey guys, played a game tonight where my opponents werewolf pushed my ball carrier and for some reason unknown he got a KO result causing me to lose the ball when I otherwise shouldnt have. looks like pushed into a lethal trap that wasnt there. neither of us knew why it happened.
happened in opponents turn 3 (my guys are slaaneshi seduction)
replay attached

Sounds like a bug I saw in one of my games - where a pushed player seemed to fall, along with the ball, into a pit which wasn't there: viewtopic.php?f=13&t=620

yep exactly that one. players all behind him, walls behind them
