So I was playing on Crimson DLC Map Pack with my friend, trying to get the Bigfoot Achievement (get 20 Stomp kills with Mantis)and as soon as the game started, something really weird happened, my whole team wasn’t moving. I asked my friend on Party Chat, why aren’t you not moving? “The game hasn’t started!” I said it did for me, and I am only one able to play on my team, and I went on the mantis, and I proceeded into the enemy base to see if the same happened for free kills 
On my Way to base, I get attacked by an enemy player, he was moving to, but he ran away from me into my base because I think he relised the same. Once I got to their base, I got an Overkill by stomp, and I proceeded further and I met some 2 enemies which i stomped them, and then killed the AFK.
In the video, I show all players not moving in my team, and also show the leaderboards showing players leaving.
I have played a game for 15 minutes on a huge map SHATTER and I won in the end, playing with 1 person against me.
Why did that happen?
That was wierd man.
Here is the video, sorry for bad quality and sorry for low sound but I was using my Turtle beaches as the sound.
