Last night I was farming EP and one after another I watched the members of my fire team get the keys for defeating bosses. After a few hours, I had yet to get a key meanwhile everyone else already did. I made sure I did not have any thing in my pursuits or anything to pick up at Anna Bray. I completed multiple public events yesterday as well and did not receive a single fragment. I'm not sure if this is a bug or if I'm doing something wrong but any help would be greatly appreciated.
