Loss of some features of the MP mission

[GS-paorel]

I have made simple multiplayer mission containing few anti ground and naval actions. Some AI planes, vehicles and ships can be activated by taking off of the player plane there, the Check Zone trigger is used for that (the mission files are attached). I added new planes after the 3.001 update into the mission and it works fine now, but only if I host a game using the dedicated server. The object activation mentioned above does not work if I host a game server from the game client. Any explanation for that, please?
