Kahl's Sneaky Sabotage - Find Sneaky Factory Stuff bugged

[TheMusicInTheVoid]

The caches aren't appearing at all. Where they should be you can hear the "humming" sound, but no caches to be found. They don't seem to be just invisible, because I tried blasting the plasma torch and slashing everywhere, but didn't get a single cache for the challenge. They also don't appear on the minimap.

Also, could we stop having mutually-esclusive challenges, like finding 10 things around the map and at the same time having to finish the mission in 15 minutes, forcing us to always repeat the mission at least once (not even counting these bugs)?

They appeared for me after trying the mission a second time. I was going to bug report it, but loading into the second run fixed it for me somehow.

I also noticed that when they were invisible/bugged, there was one in the map that spawned normally (in the latter half of the mission).
