Using my warlock character, I have had to repeat the adventures on Titan twice now, why? Adventures were completed and when I came back the next day, it shows them as not being done. Also, story line is not consistent - I was able to access NESSUS with one character early on, after completing the ZAVALA quest. (titan character). When I completed that quest with a Warlock, nothing happened after completion, except that I had to repeat it the next time I signed on. After completing it the second time, NESSUS appeared. And then in the DARK FOREST, the titan character had to fight FALLEN; the warlock had to fight the TAKEN. Is that possible? thanks
