I'm having some really weird quest behavior on my titan. I started both the Xeonology and Dawning quests on my warlock, but when I switch to my titan, I can't complete Xenology, and I can't get Eva's oven. For Xenology, it's on step 2 of 2, "Return and speak to Xur." I don't have an exotic cipher in my inventory. However, when I go to Xur either in his treasure hoard, or where he currently is on Nessus, there's no option to turn the quest in. Normally it won't let me [i]not[/i] turn the quest in. For the Dawning quests, I have the Cookie Delivery Helper on my titan, and it's on step 1 of 7, with no progress made on that step. Eva gave that quest to me, but she hasn't given my titan the oven. My warlock has the oven, but I can't progress bounties and the other Dawning quests for my titan while I'm on my warlock. I have already tried abandoning that Dawning quest and then speaking to Eva, (who didn't re-give it to me) and then when I got it from the quest archive terminal, it neither gave me the oven quest nor allowed Eva to do so. I'm not sure how to un-bug my titan at this point. Has anybody experienced this before?
