I do not have any save for this bug, but it is pretty common and anyone who played Heroes a decent amount of time has experienced it. Basically, when a troop attacks a Cyclops/Medusa/Unicorn, the Cyclops/Medusa/Unicorn will reteliate and they have a chance to paralyze/pietrify/Blind the attacking creature. But if the game calculates that the attacker should get Good Morale, the golden bird still appears over the immobilized creature, even though it won't get a turn. The game doesn't check for paralyze/pietrification/blindness on the creature it wants to calculate morale for and that leads to some minor bugs like this.
