Twice now I've leveled, went to change my skills to new ones, and when I accept them I notice they weren't changed to the new ones. But on further investigation I am actually disconnected from battle.net (no interactions work when clicking anything)... yet I am still walking around in a world that does not react to anything I do. I then have to force quit the game and reconnect to battle.net, which takes a long time right now. Seems weird that the only 2 times it has happened were both immediately after leveling up.
