At this point I'm almost convinced this bug is related to me getting S ranks on certain champions. Literally every time I do extremely well (good cs, good ward score, good KDA), I get nothing instead of an S/S+ rank (S- still works fine).
This is probably the fifth or sixth time. Makes me want to bite my own arse.
I know i'm going to ask you a really stupid question like "have you tried turning it on and off" but do you own Akali? Because i've never seen this happen to me. My last S was on 23rd on Janna, ARAM. If this actually happens, i reckon this is a bug and an annoying one at that. It's a wasted opportunity to not give you a possible S and have to make you do the work, again.
Yeah its a bug, it happened to me s- works fine
Yesterday i ended 9/0 and 6/0 doing objectives and good farm aND ''Mastery undefined'' Seems to happen below Mastery 6 Only in Mastery 5 i think
