I not sure if this is bug or game mechanic but I do not remember if this has happened before. So basically I pick up couple of exotic gear that I have not unlocked skin yet. Item instantly account bound to me after picking it up from chest and unlock the skin even if I have not interest in doing this. Every item was picked up on fractal and like I said before I’m not sure if this is a mechanic or a bug so sorry and correct me if I am wrong
