I was on my titan doing the Means to an end quest mission "interference" and I beat the shrieker at the end of the part I was at. It led me back to Eris and told me to talk to her (in the quest menu) and it wouldn't let me talk to her. I waited for a while and then just returned to orbit. Now, the quest isnt in my inventory AND i cant go back in the mission until I progress the quest. HELP! Edit: I was at the end of the quest when there was 500 seconds and it wasn't working so I left not wanting to wait 500 seconds
