I'm playing on my warlock, which was made around a week ago, and it appears that I cannot complete the season of the lost, splicer, or chosen weekly quests because I'm stuck at the step that tells me to go to the umbral decoder and pick up the "decrypting darkness" quest. However, when I go to the umbral decoder, nothing is there. As a result, I also can't focus or obtain umbral engrams. I'm confused as to why this was happening because as far as I can remember, this hasn't happened on my titan or my hunter, and I'm pretty sure I was able to focus umbral engrams last season on my warlock. I checked the abandoned quests kiosk but it's not there.
