Topic name says it all really: 9 legendaries i’ve got from trading 20 mythic fish in -which i left on the floor- dissapeared and weren’t mailed to me like it happens with any other legendary that drops.
That’s just bad luck. Waiting to get items mailed to you is a risk in itself. How long after did you check your mail? Have you gone back to the zone? If there are others still fishing I’m not sure it that would effect the time.
