Wrong command

when click product orders npc say wrong command?
what causes it?

Looks like your clients interface.pck does not fit to this window. It had the wrong button ID. Dunno if its really in interfaces.pck or in elements but i whould say client doesnt fit to server at this part.

I believe whether you need a repair on the item or container in the forge.

i think need activate this npc produce in elements.data [ NPC Crafting list 53 [ changed row 3 (int32) from 1 to 0 ] @ sELedit ]

thanks all
turns out the problem on the options that are not suitable items on accesories
