Invincible and Invisible mobs

After closing unstable breaches the breach mobs that were alive in there still able to attack from the Breach domain but because of the breach being closed they cannot be attacked so Invulnerable and Invisible mobs chase my character all over the map.

3 weeks, and no post no nothing about Vengeful Avengers mod removal, so I assume we can't do delirium in our maps this league, with breach at least.
