The Strange Gift function where you exchange a strange coin for a random piece of gear appears to be bugged. Xur is giving out only Red War stuff. I hadn't used it since before EOF but back then, I was able to get random pieces of purple gear like ketch-killers and such. Just used about 60 coins today, only got enhancement cores, raid banners, and mostly blue weapons and armor from red war, not getting anything else. I posted a link to my video
