Unable to Load Champion select in aram

Yesterday night I queued up for aram, and when I found a game, I was unable to load into the lobby and see what champion I was playing. Being frustrated and tired, I closed my league client after 20 seconds, and decided I would just go to bed and take the lobby dodge penalty, as I wasn't going to be playing in the next 15 minutes anyway. ( I always get 15 minute dodge penalties straight away, but that is a discussion for another day) This morning I logged in and had a leavebuster notification waiting for me. After typing " I agree" (even though I don't, as I hadn't been afk at all) I checked my recent games to see which had triggered it. That ARAM that I thought I had queue dodged showed up as my most recent game, and was listed as a leave. The bug I would like to report is that even after closing out of my client via task manager (as league went unresponsive) and ending all league related tasks (pvp.net patcher and what not) my account was still connected to the lobby for some reason, and it was uncontrollable whether or not I could leave. As a direct result of this bug, I got a leavebuster warning and I will now need to be careful of this bug in the future, so my playing experience is not hurt by a long duration ban being administered unfairly due to a bug. Please look into this, thank you. Summoner name: Fancy v2 Bug type: connectivity/ unable to disconnect from a lobby Time of occurrence: About 11:40PM EST 12/5/2014
