I just finished the legendary Witch Queen campaign for the second time (this is the first time for this character, my warlock, my first run through was on my titan). I was able to interact with Mara Sov and start of queens and worms on my titan, currently sitting at step 10/17. I wanted to start the quest on my warlock but when I go in to the enclave after talking to Ikora, Mara Sov is not there and there is no way to start the mission. Ikora is no longer here either. I already swapped characters, logged out and back in, and Mara Sov is still not there. Possible issues that I think may have caused this: 1. When I finished the campaign for the second time, my character was completely full on Resonant Alloy (80/80). This meant that I could not accept the Resonant Alloy from Ikora and go talk to Mara. To work around this, I went into the enclave, crafted a new weapon, and went back to Ikora with 75/80 Resonant Alloy and I was able to accept it this time. However, when I went back down Mara Sov was not there. So it might have something to do with the fact that I was full on Resonant Alloy the first time I met with Ikora. 2. I ended up accepting the Report: RELIC-DATA quest from the Evidence Board before heading down into the enclave. I believe this may have somehow taken priority over Mara Sov as it just shows one of the blue diamond - white crown quest markers over the relic which I assume corresponds to this quest. I am on a PS5 Digital Edition. Playstation is terrible for exporting videos. I used the save recent gameplay function to record the entire ordeal but currently do not have a way to get it off of the console. I will work on that if a video would help you diagnose the bug. Thanks for all the hard work, love the new expansion and campaign!
