Not getting a hextech chest after an s-
Hey, so I really suck at leblanc, but I'm trying to learn. I don't believe I've ever gotten anything below an a- on her in my games, except for last game! I got an s- on her. I have 3 chests available, bu8t I still didn't get my hextech chest, is this a bug or is there a reason for me not getting the chest. 1. I have chests available, 2. I've never gotten an s with leblanc before. I was kinda excited that I could get another chest, and was pretty disappointed when I didn't, is there a reason or a way to fix this? Thanks!
