Friend Gifting bug

I have tried to mystery gift a friend multiple times, and have gotten different errors each time. I tried gifting and got this error: http://puu.sh/mKZaj/1e68219b60.jpg we then tried playing a game with them playing Cait (lunar revel skin) it wouldn't let me gift it in the post game lobby either. We then re-friended eachother, which we've been friends for over two years, and played another game. Tried again and got this: http://puu.sh/mL3Cv/a78a3f5bce.jpg I got home from work and tried one more time and got this: http://puu.sh/mLXIo/299f301a42.jpg After waiting a day when we re-added eachother (now with Facebook confirmation) it worked with no issues.
