1. rank twisted crashed
2. we are winning and dominated game, after played 15 mins game frozen, mouse and keyboard not responded.
3. nothing was working i have to restart my computer and reload the game. was 2/0/6 then we played another 5 mins and win the game.

I played a few more games after rank twisted, same problem happened once. and game stuck in loading screen twice. I should get my +25 LP but I got - 10 LP.
your game crashed. and I did reconnect and still win. should give back my points.
