When I receive materials for the oven and go into my inventory, it shows that I have no materials except for Essence of Dawning. I did 5 strikes and got a variety of materials, yet I go in the oven and I don't even have a dark ether cane to make the gjallardoodles. I talked to Eva and got the items to start it, yet I can't even start it since I can't make anything. Kinda cheesed honestly :( [b]Update:[/b] So when I switched to my hunter and checked my oven, apparently all my materials are there, so my main character (my warlock) is glitched, ugghhhhh [b]Update #2:[/b] I visited Eva on my titan, started the quest, switched to my warlock, the items were there to start it, and I can now bring Zavala the baked goods. I feel so much better, if there's a will there's a way [b]Solved:[/b] So if you pick up the oven on one character but don't do the first quest, then switch characters and use all mats on the second character, then go back to the first character, the mats will be missing unless you can obtain the first mats from another character, which is how I solved it.
