This is the WORST BUG EVARRRR!!!

So I was dumb enough to listen to someone in champ select. They said, "click edit masteries, then hit spacebar." so I did... Nothing happens on masteries page but when I tried to close it, the box turns white, and you CANNOT CLOSE IT LOL. Even after my game, I still had the WBOD. (White Box Of Death. )

**TL;DR Don't listen to anyone at champ select. **
