Just was in a duel with a dragon deck and he played Terror of Mount Velus. Authority of the Consuls immediately activated and tapped the Terror of Mount Velus and then he attacked me anyways and I was hit with a bugged double strike attack.

I was not expecting it to happen so I did not capture the information for a full ticket, this is the first time a monster was ever able to attack even though it was tapped so I was not expecting it and did not screen shot the bug.
