DC'D while ingame

So, like, really recently... currently. I joined a game where I chose Jayce. Everything went really well until around 13 or so minutes in to the game, all of a sudden I had disconnected from the game. I remember I was playing against a Darius, Ekko, Kha Zix, and... 2 bot laners that I forgot about and on my team was me as Jayce, Yi, Yasuo, Caitlyn and... our support (I forgot who our support was). Anyway, I had disconnected from the game, and around a minute or so, after waiting another while, I exited the game and to my surprise I wasn't sent to the recconnect screen. Instead the client sent me straight to the lobby. Funny thing actually, I was able to go in a custom game to test it out and it worked. I was able to connect to the custom game.

I wonder what happened to my previous game.

Tl;dr : Went in game as Jayce, 13 minutes later dc'd. brought straight to lobby instead of the recconnect screen.
