So the other day I got a pack of the 3 of Coins from Xür and I used 2 yesterday and 3 today. Not only did I not get exotic engrams, but I didn't get any, and neither did the friends I was playing with not a single engram during the time the 3 of Coins modifier was active. Not even a green. I don't know why, all I know is that it didn't give me anything from Skola, Crota, the Warpriest or the Crucible and Iron Banner. It's ridiculous and I know Bungie won't "refund" or send a pack of 3 of Coins back, but they can at least look at my account, isolate the problem and then fix the bug because this was kinda frustrating to just assume it was a random chance that the 3 of Coins disabled engrams, then find out it did it for the entirety. I have gotten engrams while the modifier was inactive however, though that is totally unrelated.
