For pretty much years now Drifter and Xur in the treasure hoard, and as of late Ikora, have been pinging me for literally no reason. When I go to visit them there are no items to collect from any of them. No engrams, no enhancement cores, no cosmetics and I have triple checked that it isn't me being full on enhancement prisms, ascendant shards, or upgrade modules (none of which I'm full on anyway because I spend them). I have no clue if anyone else has been experiencing this or not, but it's been a bug for me for ages now that doesn't want to go away so I thought I'd make a post about it. Hope this reaches you guys.
