Bakonawa Extermination Quest Error?

[Checkmate]

Im sorry if this topic was in wrong section and please to move it ot correct section..

I'm using latest rathena version... Which is held and Bakonawa quest...
But it seem like the item belongings was not drop at all from Tiyanak monster.
It was say in :

 

 

 

He tells the player that Tiyanaks carries those belongings and asks the player to retrieve 2 Lost Belongings from Tiyanak and take them to the Missing Person's Father. (malaya 270, 267)

From : http://irowiki.org/wiki/Bakonawa_Extermination

Im trying to bypass it using GM by give the 2 Lost Belongings to player but the ncp name Missing Person's Father. (malaya 270, 267) cannot detect the item.. 

Now how can we solve this... If really the item did not drop from tiyanak?..?

Anyone face this problem?..?
