I'm stuck at 3/4 Brawlers Purchased
So, I've played 8 games since starting the last step of the TF/Graves icon, and I'm 100% sure I've bought each of the brawlers at least once, but the counter is still stuck at 3/4 Brawlers Purchased. Is there any way to tell which one it thinks I haven't bought? Or do I have to win the game that I bought it in? Or what?
