So i won the game and lost LP...?

Riot explain.

So basically, I started a game and everything went well until my game crashed quite early in the laning phase, I had crashed twice in a row while trying to reconnect so i had to restart my pc and it took a little time but i finally reconnected into the game, even though I was behind I managed to keep pace with my team and we ended up winning the game. After we won though, i ended up losing LP.

I'm not really upset hence it is the end of the season and I won't be climbing much further in this short amount of time. The only reason i am reporting this is so it never happens again, to anyone.
