so i dont think i have encountered any, if i did i skipped them as i was beelining to the end to encounter them, if they where in the middle of the mobs it was hard to notice them, if that was the case, locking the portal until the player kills the bosses will make them look around for the problem. i gave up a bit after the long walk i had to do without the car and went thru the warzone and when i went to the place with a hundred portals i had to change games as i wanted to rate more entries.
