My friends and I finished Crota yesterday. We selected it through the weekly raid, finished both challenge modes, and killed Crota. None of us left and we all started and finished the raid together. However, only some of us where able to get the new shader from the kiosk from killing Crota in the new 390 LL version. Myself and 3 others where not able to pick it up. It still says we have not killed Crota. I was even the fireteam leader so it's really weird that even I wasn't able to grab it. We went to orbit and checked the map and it does say we have all done the weekly raid so it registered. Can this get checked out? Obviously we'll eventually end up killing Crota a lot more but it would be nice to not have to leave it up to RNG.
