Trist bug plus Music in game bug

I'm really sorry I've no proof because I didn't think I'd ever encounter a bug, but I was just testing out the new Tristana in a bots game and I was in the middle of combing (E Q Ghostblade) and my attack speed went up to 2.71 for a split second, but it didn't just say it, my autos were much faster than they were when i tried it again and it stopped at 2.5.

The other bug I encountered is about changing the Updated music to the Classic music. Once you changed it, you're unable to change it back instantly it takes nearly 5 or so minutes for it to convert back.
