Spawn rate of random fetch tasks need serious increasing

The problem is probably that the items for those quests are randomly generated in different locations for each playthrough. I am yet to figure out if those locations are set in stone the first time you land on the planet or they shuffle again every time you load the map. So far I believe they are generated once and then don't change. I suspect that they may not spawn properly. In my first run (before patch 1.05 though) I drove around Voeld for hours, visited each kett camp multiple times and still didn't find the items to finish two of the quests. In my third playthrough I had the luck to finish all of those quests on Voeld simply because the spawned items came one after the other in every single kett camp I passed while driving to other quest objectives.

You can still complete the "Gone Dark" quest, even if some bugs can't be scanned. You just have to find the ones you can scan. I did it yesterday and had two locations where the bugs were glitched, but then found other spots with no glitches and finished the quest. So there are probably more spawned items than the minmium required to finish the quest.
