I do know that, after feeling Eva and receiving the oven and quests, I played 3 gambit matches and didn't receive a single material. That's when I decided to log in to my other two and had trouble starting the quest with them. I reset the Xbox and finally, my warlock (main) received materials from kills. Then I could not find the oven with my hunter, finally found it on Eva's page 2. It's just weird that the main component of this even is stuffed on page 2 when it's a critical part of the dawning even lol. Thanks for the help though, happy hunting
