Hola, So was playing last night and when I ran the Larfreeze event..I could only see myself and another player, yet there were 4 players showing up on the group and doing damage. Same for Earth 3 - Injustice system. Ghost players I tell you.
Had the same problem today in the E3 Duo during the 1st Boss. I saw the Robot Sidekick; but no player. PS4
