I've had the same thing tonight. The problem is that the game doesn't tell you that your actually not getting the gun for free as per usual. Instead, each one you accept costs you legendary shards without it telling you unless you look very very closely at the transaction. I've been grinding all night and have lost all of my shards to this shoddy game mechanic and because of that I'm throwing in the towel as I absolutely won't put up crap like this. I have better things to do than waste my time on this. Apparently, making this comment will likely get me banned from the forum now so I hope you see it before it goes. I feel your pain! 😡
