Well another weekly challenge datapad issue. Unlike the ones for Vanguard Supply Recovery - II which I may have already collected, I don't think I have run a contest of elders this season, though possibly I don't remember but did a run and no datapads spawned at all so Fireteam Missives Discovered - II is also impossible to complete. Other fireteam members did spawn them, so don't know why they are not there for me on this one.
