Grineer caches not spawning

[(NSW)Simtron]

Plains bounty sub-mission called "Find Grineer caches". The mission variant on the mountain Grineer base. Been in a couple groups and encountered this. Caches cannot be found on the surface or under in the cave. The only cases I can think of is that either its a bug and they don't spawn, its a bug in the waypoint system that misguides players, or the caches are so well hidden that no one can find them.

If the caches are in fact intentionally hidden, the waypoints are left intentionally misleading, or/and they are hidden so well that mostly people can't find them even with internet help, then maybe this game mechanic needs to be revised.

Just did this mission too and i'm 200% convinced the caches simply didn't spawn in the tiny cave, nor above it nor on the stations roof.
I use Thieves Wit and it didn't indicate any other loot sources on the mini map either.

IIRC, there was a bug a long time ago where one of the caches would spawn on the terrain outside/above the cave, but it's hard to tell whether they don't spawn or people just haven't found them.
