Not sure if this is strictly a bug, but you can't tab player names if you have sorted them by Tier. You just end up tabbing the gens. I can't really put screen shots, but if I typed "a" and pressed tab, I'd get "All Gens". Press tab again, I get "Advance." Same goes for r with "RBY" etc etc. This has been an issue for like, ever, but I was just too lazy to post this. Its not really a bug in the sense that Tab isn't working, it just removes Tab's functionality.
