Bug where everyone was in slow motion for the first 15 minuites of the game.

not sure how to send a replay link, because i havent updated to the new server yet. But everyone was walking in slow motion, including the cooldown timers and even the clock time. This occured for about the first 15 minutes of the game. Auto attack animations were normal, but attack speeds were just as slow as the game. It was actually kinda cool, very easy to farm with, but hard to land skillshots, as people could see the skillshots coming from a mile away, and have plenty of time to dodge. The skillshot animations were slow as well. Cant say it was unfair, as it affected everyone equally. But i was playing as zed vs a veig, which just gave me an upper hand in lane ---___/--- (i have no idea how to do that symbol)
