Abomination boss bug

If you get "The maven inferferes with players" mod in this map, at the final boss if maven spawns the twins of terror or the shadows I don't know what is called, when those shadows vanish it counts as one of the 3 bosses dying, spawning the final boss prematurely. You can end up fighting multiple of the same bosses ghosts because of it. It also does not reward map completion if you kill the final boss. Adding screenshot of 2 Doesdres shadows hitting me next to the last boss corpse.
