Map Geometry Issues on Allegeheney Square Map

[Tarakas]

This map is the second mission for the Freaklympics mission arc. The last captain is almost always hidden. Also many of the enemy groups are hidden until you are right on top of them.

[Rudra]

That isn't a map geometry issue. That is a render limit in play. That map doesn't render all the spawns because of the render limit. So you can see the Freak' captains comments when you get near, but not find them until you have removed enough of the other mobs for them to finally be rendered. Or in your case, having spawns suddenly appear when you reach them.
