Both the Exo Stranger and Xur (in the Treasure Hoard) are flashing as if they have something for me to claim, but when I interact with them, there is nothing. They also show up as green "person" icons in the destinations tab, indicating that I should land at their respective locations. This issue has been going on for a while now and it's starting to annoy me. Is there anything that can be done to fix this issue?
