Masteries and runes

So i was playing a game the other day with friends draft mode normals and i made some new runes and masteries before the game because i wa spretty sure what i wanted to play. We queue up and its my tur no ban but i notice my masteries AND the runes dont show up. I chekd a couple of times and decied i will just make some before the game it wasnt a big deal. The masteries didnt save and i couldnt change any of my others to the ones i wanted. I dont know how often this happanes but i was extrimly upset and had to doge a game since i couldnt play the campion i wanted since ididnt have mastaries nor runes. I reloged and the bug had fixed itself all the runes and masteries were showing including the ones i made in the lobby. Plase make sure this doesnt happaned again. Sorry for mybad english not native :)
