Monster nests south west of fort astre ruins

[Merkavar]

Anyone else not seeing the nests? two nests with in spitting distance of each other on the map but when I go there all I find is centipedes but no nests to destroy.

I went there previously for quest big game hunter. Should I have gone there first and destroyed them then done the quest? Is there another quest or contract that involves this area?

Trying to clear them off my map.
