Riven Challenge: Find caches w/o raising alarms -- impossible?

[MageMeat]

Is this a bug? The challenge on my Riven mod calls to "find 4 caches without raising any alarms", but sabotage missions automatically alert enemies to your presence when you complete the objective. The wiki says that finding a cache undetected and aborting the mission adds to the counter, but that hasn't worked for me.

What about hive missions? Does it also alert infested when you destroy a hive?

As a temporary work-around, you might try Dakata, KoolaidKuva Fortress.

 

It's the only exterminate to have caches.

he is right, extermination on kuva fortress is the only option, i used ivara with a lot of loot radar, and kill all the dudes then looked for the caches, also used perma invisibilty

so basicaly do a normal grenier sabotage but put a cooling cell in the injector. i did it on sedna whit loky, after i found the caches i extracted the cooling cells, a inserted one to the core below and then i just guarded the place making sure no greniere that sow me survived after that i just finished the mission unseen.

Uranus sabotage works for that.

Void sabotage has no alarms, you might want to try that one.

Tried it. It was a failure.

Oh .-. Sorry.

Never had that challenge, so i'm not sure what else could you try .-.

I believe you can grab the caches, then abort the mission and it will maintain your completion count.

At the very least, the wiki still has this tip on the Riven mod challenge list.

The method I used when I had this challenge was to do a grineer sabotage with the freeze destruction so you do not trigger an evacuate timer. After the freeze, turn off all alarms, go find the 3 caches in the mission. Extract, and repeat the mission, except this time pop the first cache you find to get your 4th done and the riven challenge completed.

Edit: Holy necro post, sorry for bumping this thread that was started in November 2016

Just saw the necro post

Actually this is extremely bugged. Ivara staying stealthed total is automatically discovers in the Hive room and looses any progress on the Riven. It's infuriating to say the least. DE, please fix this S#&$.

Last time i check u can do lua crossfire i think 🤔

[DeckChairVonBananaCamel]

i believe infested activate a silent "alarm" the moment one detects you, i think it is the same for void.
Lua im not 100 percent sure about though the theory seems sound.
But i think i did a kuva fortress method once myself
