I reproduced 3 times a bug on the Praxic Sword Exotic quest, step 6 final boss, final phase. Each time I accidentally killed 2 like mobs and dropped light orbs, at which point one mob was stuck in a portal and was not able to be attacked. This repeated 3 times in a row. Because I could not kill the final orb mob, no further orb mobs would spawn. Needless to say this was timed, and as such took an hour and a half total time which was wasted. Please investigate and fix this issue. The portal/mob affected was the first wall spawn to the left immediately after entering the boss area, and was a taken orb mob. This mob would never fully exit the spawn portal, and was seen half in and half out of the portal with no damage able to be dealt to it.
