Caches not spawning in all 3 sometimes

[Chaincat]

While it is likely we simply missed them, after spending somewhere around 20 minutes scouring sabotage maps multiple times as a catabomb limbo with max loot radar, I've come to the conclusion that, while rare, it is entirely possible for a cache mission to only spawn 2 caches, with the third one simply not existing on the map, or is in a wall I guess according to a few google results from a few years back. I would hope this is an erroneous observation, but the caches being too well hidden for a loot radar limbo to find after scouring every room three times over seems a bit unlikely. I've observed this in orokin tower/derelict sabotages and hive sabotage only, but I would not be surprised if all cache missions potentially have this problem.

Some rooms go higher than a maximized loot radar.  It pays to look up at times.

I feel like I've had it happen a few times as well.  I've spent up to an hour scouring the ENTIRE map.  Pulling it up so its on the screen and maxed loot radar.  Just nothing to find.
