I tried to gift one of my friends a skin, but it keeps saying I haven't known him long enough. I have had him on my list for almost a year. I have gifted people who have been my friend for even less time, yet it still won't let me gift him. Yes I have tried a few times. Yes, I restarted the game. I even did it the day after and still the same thing. So... why is a year not enough?
