Client Crash at "AFK Test" for ALL game modes.
EDIT "LolClient.exe has stopped working" every time a separate panel is opened up that's not inherently part of the interface. AFK checks, summoner Icons, individual champion profile screens from anywhere (store, champion panel). The new champion select system is the only game mode that works. None of the others do. If I was a conspiracy thinking kind of guy I'd be suspicious of the fact that the ONLY thing working is the new, updated game mode.
Also, every time this happens its counting as a dodge/leave. I'm on a cooldown now for declining/leaving.
