A recent Mirage bug ruins his decoys and the advantage they are supposed to give him. Redditoru/Planner404 showed his dilemma in a Reddit post. It's worthy of note, the bug seems to happen in the Arenas.
While playing a match, they took a screenshot of the enemy Mirage and a rather obvious blunder. Above the decoys is the player's name tag. It only appears above the decoys, making it pretty obvious which one is the fake one. It's also massive in appearance, making it easy to spot.
This similarly happened to user u/dividedbywords. While it may not be as damning after the initial gunfight is starting. But if you're trying to make an escape with your decoys, this can be pretty brutal.
Mirage finally feels in a decent spot in every game mode, so this bug needs to be fixed rather quickly.
