Rune problems in CLASH of all things

My friends are constantly having problems setting their runes because of client issues whenever we load up for clash, and TWICE now they've had to choose default runes because they couldn't change their actual runes. One time we were lucky and he locked in katarina so he was able to take electrocute, but the other time we weren't so lucky. He locked in hecarim so he took PTA and fed hella hard, and who knows? If he had his actual runes things would've been different. Client cucks once again
