Arena Bug with Taunt

In a match vs a character named Rance in Arena just a few min ago, I found myself unable to attack with creatures midway through the match due to receiving the message “unable to attack: a taunt minion is in the way” despite no taunt minion being visibly present and I basically lost due to being unable to attack either him or his critters whatsoever about midway through the match onwards…I am unsure entirely if this is a glitch or a hack but it isn’t functional gameplay.

in such case you better restart your game
Prolems with invisible minions or similar issues almost always solve themselves if you restart
You’ll still lose some time of course but it’s better than being softlocked forever
