Boss Encounter unable to start on City Square Mirage when only 1 boss spawns inside of the mirage.

The City Square map always spawns with 2 bosses near the fountain in the center. However, if only one of the two bosses is inside of the mirage area, they are present, but in a glitched state and cannot be killed.

The bosses effects and passive damaging abilities are active, but they do not otherwise move or attack and cannot be damaged, but can damage the player.

Yep encountered this bug a lot when I was farming city square.
