Hi, i was playing dominion with a friend, when suddenly we couldn't move anymore, we could watch how an ashe, a tf and a xin zhao killed us, but we just couldn't move. One mate and one enemy said that they were lagging too. I want to reconect, but a warning appears and i just can't. My friend is trying to reconnect while i write this. Please tell me if this is a problem of mine or riot is trolling again

When multiple people in a game lose control, its never your fault.
Riots servers probably just took a serious dump or something during your game.

That thing has happened to me in the past as well. It's frustrating, but there's nothing you can do about it.
