I just completed "The Promethean Code" mission as part of the weekly story playlist. This was my first mission of the week and I did not receive the Treasure of Ages drop. My inventory was not full, I do not have any treasures left over on any character from previous weeks, it did not go to the postmaster or anything along those lines. Oddly enough, I received 35 marks from the completion as opposed to the normal 20. My marks have not been close to maxed out all week, so I don't think it's anything along those lines, but it is interesting that that happened and I did not receive the treasure. Maybe the extra mark drop ate the ToA drop? Has anyone else experienced something like this?
