[CLASH] crashed and picked random champs for both teams

https://matchhistory.eune.leagueoflegends.com/en/#match-details/EUN1/2394000993/221288611 I played urf with some friends and it went toally normal until losers bracket last game. When in champ select (2nd ban phase) the game crashed looking like as it dodged. [Crash happened to both teams] after 2 mins of waiting in a black screen the game loaded us into summoners rift exept with champs that we didnt chose. While i was olaf, my intentions was to be mid but i got picked into jg as olaf. which was my original jg player's pick.

after we got into the game we chatted with the enemy team about this bug and they were as frustated as us, they got leona jg(which was their support) eve and ornn (which both were unintentional, and they didnt know how to play them) we ended the game in 15 mins after they opened.
