When you did it first try but forgot to equip Dark Sense.
I guess I am a lucky person. Just got a match with a farming Trapper. He did his 4 Bear-Trap challenge and I did my 3 gen challenge.
I tried to go Dark Sense, Deja Vu, Bond and I forgot the 4th one. I get into the lobby and I get a message from the killer. He's helping everyone out with their challenges.
So I get to do my 3 gens and after game was over I realized I had Kindred equipped in stead of Dark Sense.🙄
