This is nothing to do with multiplayer, it's a legit bug, 1 player placed in editor hit preview, 1 FPS

Same issue

15% GPU utilisation, 1-5 FPS Texture LOD issues

Win 7 32bit SSD
Core2 Quad Q9400
4GB RAM
GeForce GTX Titan

Ok thanks Phalanx. The code worked in previous builds so hopefully its a bug that has been introduced recently

I'm not sure I understand you Phalanx.

Civilian unit when grouped to west will NOT be attacked by east, which is the opposite of what you have described.

Coder error please close

Heres a test script I put together for this issue. I believe it effects any setBehaviour type and not just SAFE. This bug means AI exiting a vehicle never reach unitReady true. Removing the setBehaviour line below fixes the issue

• spawn

{
private ["_group", "_leader1", "_unit", "_vehicle", "_continue", "_boarded", "_disembarked"];

_group = createGroup east;
_leader1 = _group createUnit ["O_Soldier_TL_F", getPos player, [], 0 , "NONE"];

for "_i" from 0 to (3) do
{

		_unit = _group createUnit ["O_Soldier_F", getPos player, [], 0 , "NONE"];

};

_group setBehaviour "SAFE";

_vehicle = createVehicle ["O_Ifrit_F", getPos player, [], 0, "NONE"];
_group addVehicle _vehicle;
units _group orderGetIn true;

_continue = false;
while { !_continue } do
{

		_boarded = true;
		{
			if!(_x in _vehicle) then
			{
				_boarded = false;
			};
		} forEach units _group;
		if(_boarded) then { _continue = true };

};

diag_log "ALL BOARDED";
sleep 2;
_group leaveVehicle _vehicle;

_continue = false;
while { !_continue } do
{

		_disembarked = true;
		{
			if(_x in _vehicle) then
			{
				_disembarked = false;
			};
		} forEach units _group;
		if(_disembarked) then { _continue = true };

};

diag_log "ALL DISEMBARKED";

{

		diag_log format["%1 IS READY: %2", _x, unitReady _x];

} forEach units _group;

};
