NPC Problems: "You do not have this object"

[MUTANO]

My NPCs are in a certain problem when the item they are buying are grouped.
For example, if you sell products of creatures like the hydra head, if you have more than one unit grouped the NPC returns "You Do not have this object.".
This is too bad because one problem is affecting all NPCs who buy items of that type.

The version is 0.3.6 The Forgotten Server (8.60)

I wait for some help ...

Thanks.

Has already achieved.
For someone with the same problem, just download the original TFS 0.3.6 and get the folder npc / lib to replace by that of his Server.
