I was in a match on my alt and for no reason, I started to lag terribly and I lagged out. After that, it said I didn't lose any rating on the defeat screen. In the lobby, I could not go to the armory or my profile page. I refreshed my page and got back in the lobby and I lost my rating even though I lagged out for no reason. It went fine but that terrible lag came out of nowhere.
What the hell happened?
