I have 50 dwellers out exploring permanently and before the update I was getting legendary items quite regularly... So much so that the first line of defence in my vault is 14 dwellers with fat men, mini guns and a missile launcher.
Since the update my explorers no longer find ANY legendary items. Best weapon they find now is the plasma rifle, clothing stats maxed at 5 special points tops.
I've had a couple of legendaries from lunch boxes, but nothing from exploring. Am I bugged or have things been "rebalanced" to the point that exploring is now pointless?
