I was hoping that logging off last night would fix this issue but it stlll persists. I was with a group and could see all of the group loot and saw that all of the group drops I was getting were going into the group backpack. I logged out of the group to go with another group and then after that Cave fight was over, later in the day, logged back in with my origial group. Now I see on the main screen that I am gettin group drops, but only a FRACTION of those drops are actually showing up in the group backpack or at least I can only see a fracton and also only the loot that I have been putting in
