Thank you for the explanation CheeseHawk.
I'm more calm now.
When I asked about that on chat and received a laconic answer: ghosts, I really thought I was being screwed by other player and leave the room.
I was away from combat simulators sims for long time. Since the AH era and the gold years of the il2. The CoD has the potential to be the new watershed in ww2CFS though I hoped more for a sim promised for so long.
Anyway I believe that the game can take off once resolved the initial bugs.
Salute!
