(New bug with season start): When acquiring new additions to certain collections such as Mounts, Mount Armors, Mount Cosmetic Trophies , and perhaps other sorts of collectibles as well, the Glowing Yellow Diamond Minimap Notification Icon refuses to go away , lol.
I don’t think this functionality is working as intended. That minimap icon just keeps coming back automatically regardless of whether or not the player mouses over, clicks, or even equips, newly-acquired collectibles.
Seen on: PC, Windows 10, Battle.net client, fullscreen display mode
