I can't collect keys after getting 4 chests
It seems like I've been playing 9 games in a row with wins for all of them, and I didn't get even single key fragment. The last key fragment that I got was when I had only 3 chests and since the moment I got the 4th chest I didn't get any key fragment.
Someone know anything about that ? Is that a known bug that riot's going to fix ?
