Anybody got a quick answer to why some planes follow their path but others fly around in circles? All have the same action.

You should have posted the code that you are using, this way it's only a guessing game: Some of your planes do not get close enough to their current path target, then they try to turn around but as the angular speed is limited, they never get the right angle and thus always fly around the current node.

Here's the action code:

Code:

action bomber_target
{
	wait(1);
	c_setminmax(my);
	my.fat=off;
	my.narrow=on;
	
	plane = me;
	
	my.transparent = on;
	my.alpha = 100;

	my.enable_shoot = on; 
	my.event = my_hit;
	
	ent_handle[my.ent_id] = handle(me);
	
	if(my.my_path==1){
		path_set(my, "path_001");	
	}
	if(my.my_path==2){
		path_set(my, "path_002");	
	}
	if(my.my_path==3){
		path_set(my, "path_003");	
	}
	if(my.my_path==4){
		path_set(my, "path_004");	
	}
	if(my.my_path==5){
		path_set(my, "path_005");	
	}
	
	path_getnode(my,my.start_node,my.temp1_posx, null);

	move_bomber();
	
	while(1)
	{
		my.path_dist = vec_dist(my.x, my.temp1_posx);  // close to node?
		
		if(my.path_dist < 85)
		{
			my.start_node = path_nextnode(my,my.skill2,1);
			if(my.start_node == 0) {
				my.start_node = 1;
			} 
			//if the last node was reached, start again with the first one
			path_getnode(my,my.start_node,my.temp1_posx, null);
			vec_to_angle(my.temp__pan,vec_diff(my.temp2_posx,my.temp1_posx,my.x));		
		}
		
		wait(1);
	}
}

The solution was simple.

if(my.path_dist < 200)

maybe you can do some better solution:
if(my.path_dist < my.bomber_speed * time_step)

MasterQ32 is right, your code could still fail on lower framerates.
Btw I still think my guess was right, the assimilation of my.pan to my.temp__pan is too slow.
