Bug report - Dialga VSTAR
I was frustrated to need to concede a ranked game today when my active Dialga VSTAR just floated mid-air (as cards on field do when they are attacking) after I selected Metal Blast to take my final two prize cards on my Star Chronos second turn. Prior to the game freezing I had also selected the thumbs-up icon to send to my opponent. When the game refused to process my attack, play passed over to my opponent, who then had their turn. My opponent didn't complete a win condition, so play passed back to me. I was able to play cards from my hand but not attack or retreat with Dialga VSTAR. When I went to pass my turn, I got the notification that I had Pokémon on field with attacks that had not been used (Dialga VSTAR). I conceded the game after a second turn of not being able to play.
Is this a known bug?
