You have crashed from the game. Please Reconnect.

Okay so normally I don't post anything on the forums or on Reddit but for this particular thing I did both. I don't like coming to the forums. Anyways today was playing a few games nothing spectacular happened just normal games, played a few ranked, and then went into a duo queue game with my friend. This is when everything went to crap. I got to the loading screen, the game started and I was still at 100% loading screen...so I was like okay I'll close the window and do the reconnect. I tried to reconnect and it said that the game had crashed. Tried it again one more time. Same result. So I closed League completely and the game legitimately would not let me log back in. Okay weird after about 5 attempts at logging in where it said something about authentications failing I finally got back on reconnected to the game it crashed yet AGAIN. After that I finally got to 100% and the game let me in...and wanna know what happened next? It said I was disconnected due to inactivity...are you serious Riot? Finally got into the game and it was almost 10 minutes into the game...is this some kind of bug that I should be aware of that other people are experiencing where the game won't reconnect and keeps crashing? Also, why is there no safe period to leave the game like in Dota 2? I'd rather not waste 10 minutes of my friend, my teams, and my own time trying to load into a game that keeps crashing for no apparent reason. I love getting into the game finally to have everyone except my friend complaining about how they too are in provisionals and I just most likely cost them the game. It's really not fair to me or anyone else. If there is a fix to this please let me know!
