I got to the part after the cathedral, where you're supposed to stack on the payload, so i did, then when it started moving the chat said "You will be kicked if you remain inactive" But there were no omnics or other enemies nearby at that time so i coulden't shoot at anything to remove the "Inactivity" and got kicked from the game.
That has to be some form of bug right? I mean i was walking around, and had been shooting up things throughtout the mission until that point. :/
Just kinda ruins the fun if you're kicked half way through and you don't know why it marks you as inactive.
