Having problem with "Silent Eliminator" for first time(did that before no problem).

[Zilotz]

I did Sedna- Adaro with Ash(no mobs seen me at all, they all were dead before seeing me).

I did Eris - Saxis (Infested never trigger alarms).

But still it doesn't consider as finished.

Am i doing something wrong or its a bug?

Infested seems to be always on alert, I tryed before and didn't work.

I did this challenge on  Narcissus, Pluto  with Loki with Hushed invisiblity and a Vulkar Wrath with a veiled riven with "undetected" condition. Both succesiful.  

One of my claneer did it without any stealth - just Rhino and Ignis W and killing all before they reash panic button, but another sayd that even without rusing alarms challenge failed.

Success happened today - Lua extermination on kuva leech-controlled mission without any stealth.

Looks like it just bugs sometimes - no real reason known.
