silkroad-R lamp quest

Hi, I made script with genie’s lamp quest. On the first run around Hotan quest is taken without any problem. But when my char has the dirty lamp and walks to npc Dasra to exchange for gold lamp nothing happens. There is some options what i can choose like gold lamp or some stones, my char is staying few seconds doing nothing and leaving npc without anything. I only got info that the quest is done. How to force phbot to exchange dirty lamp for gold one? Any ideas? Thanks

Is this a private server?

yes, it is entropy-sro, silkroad-r

It does not support choosing the reward.
