never ending Chyme

during act 3, and while attempting the quest to open the Waterways of Matlan, i came upon a spot where Chyme mobs were re-spawning Endlessly!!
i am serious, i stood for about 12 min letting the skeletons kill em, and they just kept respawning, they even followed me to the next area.
only way to get rid of em was i had to lure them very far back and then roll my way out of there until my skeletons re-spawned near me.
i took a screenshot of the map where it happened.
but i have no idea how to place it here, it was near the end of the map, right before the map boss area and the final lever.
if someone can tell me how to post the sc, i`ll be thankful.
