Anvil challenge, second boss.
About half or more often, when I get to the second boss and get him down to his second gas attack, he fires, but no damage and no miss is shown. Then it’s no one’s turn and we all stand around.
I then restart the game and try again. Sometimes it happens again, sometimes I get through it.
The picture below is an iOS screenshot after the problem occurs. No one’s turn and nothing highlighted.
Although it shows as being the boss’ turn, he’s already done his gas attack.
