If my memory serves me right, this was the case in the early versions of the game. And this happened because the opponent is most likely a newbie and has a version other than 3.2.
And different versions shouldn't connect anyway. Although, 70 gremlins at the start :smile20: or visiting objects only with a true commander, otherwise, a pop-up guard in the form of 5 titans from Pandor appears :eek: ... I remember that.
This happens when the computer is losing badly.
