Game Crashing (Mac) and then Banned for "Leaving Game"

Greetings.

Yesterday evening, as I came home from a long and exhausting day, I was excited to sit down and continue playing in the new Summoner's Rift and associated jungle. I queued as normal, I decided today would be a day of hilarity with Kalista and Jinx in bot lane. The game proceeded as normal until about 17 minutes, when Kalista ult'ed my dying Jinx to safety. This would prove to be a fatal mistake.

As Kalista's ultimate went off, the entire game froze like Buffalo, NY during the Holidays. Nothing was moving but my cursor, and the ever enjoyable Summoner's Rift background music was looping the same second of sound. During this dramatic moment of sudden freezing, the voice client I was using continued to function normally; and my allies (from the opposite side of the country) could be heard with unrivaled clarity. This led me to believe that this was indeed another infamous LoL malfunction.

Upon hard restarting my computer, it was brought to my attention that the Kalista ALSO suffered the Great League Ice Age of 2014 at around the 19 minute mark. The Kalista had to suffer through five minutes of haggling with Task Manager in order to close the horribly confused LoL client. We both desperately tried reconnecting, but as our Ship of Endless Struggles limped to the finish line with rats leaping off either side, our team surrendered the game. This immediately deposited ourselves and our hopes and dreams into the Post-Game screen.

To add the icing to this terrible fruit cake, I received the delightful message that I was banned for a few hours for being "AFK" during a game. If "AFK" refers to being forcibly ejected from a burning ship, to which I clung to with desperation, headed straight towards a black hole like the recent blockbuster hit Interstellar, then I absolutely deserved that ban. However, if you have been reading this thread, you can understand that my intention was NOT to leave the game and abandon my allies. In addition, my ally, Kalista, received no ban. Where is the logic, Riot? Where?

So what's the point of this thread? Partially a cathartic release of my intense frustration, but also to let League know that something went horribly wrong. Was it Kalista's ultimate? Possibly. But I have been Jinx and ult'ed by Kalista and the game continued to function as normal (including not dying, seriously try Kalista support). Most importantly, the ban was unnecessary and falsely applied. Use this information as you see fit, Riot, but please adjust this horrible malfunction.

Sincerely,

Another Disgruntled Jinx
