First of all, I am French so I will speak with google translation.
I create topic, because I have the same problem since I have arma 3.
This problem I explained on forum : http://www.arma3.fr/forum/viewtopic.php?t=6868
Here's the problem :
I do not see my point on the map, nor my colleagues. This problem works only in altis life.
Help me please, I'm worried about having trouble. I have already tried to re-install my computer, as well as the game, nothing or change.
Thank you for helping me.
