Riot WTF

Soft locked Heimer in the Champ Select, then when my duo and I got into the game, his league completely died, and crashed his computer. I got Yasuo in game. I LOCKED HEIMER. When I tried to move around, I also got kicked from the game. He lost a game of his promo series, and we wasted about half an hour. We were also in a gaming cafe paying for the time, on two computers with i7 seventh gen processors with nvidia 1080s and 3600 ghz 16 gb ram. So Riot, wtf?
