Defeat Targets II - Guff not counting

Hi there !

I'm trying to get 24 challenges in order to unlock the aura, and was intensively farming the Syndicate. I'm currently at 23, but i can't manage to achieve the last one, driving me crazy.

I've been killing my 3 stars Guff "Tiny" Grenn for almost 2-3 time, trying to execute him at max rank, but i can't validate this part of the challenge.




As you can see above, on this screen he was already 3 star when defeated, and the line doesn't get green. I also tried to put him as leader of a faction, and validated th "Defeat Targets IV" but nothing changed.

Edit : The defeat Target III didn't counted either, as I killed Guff in a Research lab and it doesn't count either :(

How could I proceed ?

Kind regards,

Merenz

I think he has to be main in the group and/or killed first. Most likely the former. Just continue having him at max rank and hope he will spawn again. I guess you can also manipulate your Syndicate board to increase your chances but I can't help here. You can also do it in party, I think. Or try for another challenge if you only want 24. Beasts one seems fairly easy. You can ask friends to share their Einhars, do your Atlas Objectives, use Scarabs, buy Einhar Prophecies...
