Bug with Nibble trick

In pvp, I've had two instances where the game crashes after using the Nibble trick to kill a target with 1 hp, but it will struggle generating the card and the game pauses. I get no generated card, I cant even pass the turn. The timer runs out and nothing changes. I can view cards and tap on them in the clip, but nothing else is functioning. I have to concede to get out, which sucks for rank.
