sitting at 44 fragments. and have no idea where the last one i need is. been sitting on 44 for 2 weeks now. i have followed Youtube videos... and all i can say is maybe it is the other 2 tier 3 bosses (other than this weeks Crota, i got it) , and the random Eris Mourne bounty/mission for Court of Oryx (which is currently sitting at "beat tier 3 boss in 2 minutes"). i swear i've already finished one though. i can't really check the fragment hunter website because it shows i have found 47 of 50 on my account . warlock is at 38 and hunter is at 31.
