Just played the daily heroic story, lvl 20, Ishtar sink on Venus. Was using my lvl 20 Titan. Apparently the rewards for beating the mission were to be a ship upgrade, which I did not receive. Was wondering why that was. I was playing with a friend; DeadShot754 he also didn't get a ship upgrade. Someone told me I should try it again with my other lvl level 20 character, a hunter. I did, and at the clear screen, I received nothing. Bug reported. Good luck.
