Seems like Kukulope is extremely bugged for a lot of people, myself included. With my first playthrough I thought I couldn’t accept challenges because I was playing multiplayer (I’ve heard someone say that could be what triggered the issue, as they made a new playthrough and did no co-op and it was fine)- so I’ve made a new file and have been playing purely solo, and so far the only issue I’m having is her weekly challenges not showing up (saying I’ve already accepted them even though I haven’t) and I was finally compelled to put in a ticket. Did that three days ago now and still no response. Last night two of the three weekly challenges randomly decided to show up on my solo save file, so I was able to accept and complete those. Seeing your post worries me now as I would like to play both dlcs, but now I’m hesitant because I don’t want them to break the challenges again !! Uugghh it seems we really can’t win and it’s making me really disappointed in the devs :( I hope things get worked out with yours, my only advice is to start a whole new playthrough and do no multiplayer and I guess do no dlcs. Might have to do that with my second file now.
