The client kept crashing in champion select and now I am being placed in a lower priority queue and have to wait 20 minutes before every game for five games . Also had 2 of my ranked games count as losses because the client kept crashing. I tried reinstalling League of Legends but I had the same problem.
Are you a Windows 10 user who got a recent W10 Anniversary update? Please have a look at these threads: http://boards.na.leagueoflegends.com/en/c/help-support/X6sPFPu8-fps-drops-and-crashes-after-the-windows-10-anniversary-update http://boards.na.leagueoflegends.com/en/c/help-support/KFxcVtYK-my-computer-is-randomly-freeezing-mid-game?comment=0000 http://boards.na.leagueoflegends.com/en/c/help-support/il5Qxm2w-if-you-are-still-having-the-bugsplat-bug-after-champ-select-read-this http://www.laptopmag.com/articles/set-compatibility-mode-windows-10
PS: LeaverBuster can't be removed no matter the context, LP can't be altered either.
SAME! After champion select game crashed like 20 times and I kept trying to reconnect and sent riot error report. Now I'M being placed in a lower priority queue (20 min). I tried everything to fix, installing wtfast, reinstalling league etc.. But still 0 fix. (I don't have such thing installed as LOLReplay.) PLEASE FIX THIS AND SUPPORT US RIOT!
