[Power Cell Carriers not spawning in Fortuna Excavation]

Had some trouble completing the Vox Solaris quest excavation part, too. It took me approx. 45 minutes, merely protecting the excavator and waiting for power cell carriers to appear. The excavator was on a slope and for half of the time, only Moas spawned. I have the Thief's Wit mod equipped and saw on the map that there were actually power cell carriers in the vicinity, but when I roamed the area, I couldn't see any. That kinda annoyed me and then, just by coincidence, I saw something from above attacking one of my moa spectres (I had positioned one close to the excavator so I could start my power cell hunt). After a bit of jumping to get a better view, I noticed one enemy standing on top of the biggest mushroom. I tried to bullet jump to him, it didn't work. I was not only low on power cells but also on frustration tolerance, so I applied my Archwing Launcher and just flew up there. Having reached the top, I was presented with a big bunch of enemies, most of which were passively standing, not even firing or trying to jump down at all! Lots of Moas - but amidst them, also two power cell carriers, exactly the ones I needed for completing the quest. Obviously, the enemies sometimes get dropped off on the mushrooms and that's why, you can see them showing up on the map but not actually catch them on ground Level. Same goes for mods and other stuff you can pick up. I am aware that there might be other bugs keeping you from completing the sub-quest, but checking out the big mushrooms for potentially 'hidden' or stuck enemy groups can't hurt.
