Act1 Cemetary no 2nd Mausoleum Spawn

In The cemetary of the Eternals i was unable to get to the other Mausoleum to kill "Asinia, Praetor Consort". after uncovering the entire map except that one tiny spot, i found more of the map to be uncovered but 2 of the potential sides were impassable to where there probably should be an opening/path
i was able to complete the quest by opening a new instance, but i thought it was still report worthy
