I just unlocked the cyclops on Beastmoon hunt, and wanted to report a simple glitch. If you put a shield on the cyclops, (Absorb 50 and +50 damage), and then the cyclops hits with the beetle spell which will steal a shield from the opponent and deal 75 damage, the shield that you put on the cyclops will for some reason be send to the opponent , and then the shield will absorb damage. This is simply a glitch that I would like staff to acknowledge.
I don't believe this is a glitch. The description of the "Thieving Beetle" spell states that it will swap one ward (meaning shields and/or traps) with your opponent.
So the mechanic of the spell seems to fit the description.
