How to remove invisible npc when input and successrefitem function used together?

[Queue]

If `successrefitem` is called after  `input` (or even `select`). When function is closed, there's a invisible thing left on the map with and 'ellipsis' (npc interaction thing) when you hover on it.
 

function	script	F_TestFuncHere	{
	input .@refine_count;
	successrefitem 1,.@refine_count;
	return; // also tried close or end. didn't matter
}

I use this function as item script.

What is calling the function?

The funciton itself its not a NPC.  This invisible npc that shows on map probably is the npc that is calling this function. So you may have to change it....

Can you post the full script for better understanding??
