Lua Items lossing actionID

[jeybi]

Hello.

I have a problem with this code

    local ritem = doCreateItemEx(reward.id)			
			
     doSetItemActionId(ritem, reward.aid)
     doSetItemSpecialDescription(ritem, "Description here")
     doPlayerAddItemEx(cid, ritem, true)

The player get the item whit an actionid and a special description, but when you throw the it into the ground it loss its properties. Do anyone knows why this happens ?

Maybe im using wrong functions, Is there any another way to create an special item ?

Thank you.
