Hextech crafting bug
Just played a game and my teams Yasuo and Soraka both received S's but I received no chest, despite not having any active punishments and not having unlocked any chests yet either.

If you didn't get an S yourself and others did it means they were not in your premade. Second paragraph states others must be in your premade when they get an S rank for you to get chests.
