Mob Sprite in npc don't walk anymore?

[Hyroshima 18]

Hey guys.

 

So, for some time I was creating an instance with interactive npcs, that walk around the map to give more immersion in the story.

I was using a client 2018, so I tried it on a newer client in 2020 and it didn't work, so I went looking for where it was working to try to resolve it.

 

maximum client that is working: 2019-05-08cRagexe  (any client after that does not work.)

 

I did the test on both rA and Hercules, i got the same result as shown in the video below.  (Left does not work & Right work!)
I am a few days trying to see if I can solve it but I have not succeeded so far.

 

code used for testing:

prontera,155,178,3	script	testeeee	1039,{


	sleep 1500;
	setarray .@x[0],151,155,158,155;
	setarray .@y[0],175,173,175,178;
	freeloop(1);
	while(true)
	{		
		npcwalkto .@x[.@i],.@y[.@i];
		set .@i,(.@i >= getarraysize(.@x) ? 0:.@i+1);
		sleep 2500;
	}
	freeloop(0);
	
end;
}
