[Crafting] Not receiving chests even though all requirements met.

My issue is that I just played a game on Morgana whom I have not gotten a chest for and I still have two available chests left and my ADC got an S- and I did not get a chest. As far as I know, as long as anyone gets an S, the whole team gets a chest as long as you havent already received a chest for that champ and you have chests available. It is a neat system, but seems to be a bit glitchty.
