Lineage 2 Kamael BOXES : Lineage 2 General Discussions

Hi all.I`m glad to register in this forum, and i hope someone can help me with this.
As anyone know in L2 if you are killing CHESTS, they after reborn is BOXES.Which we can open with Chest key.But this is not in all servers, i`m playing on private server, but here after killing chests they stays like chests.And i can`t open them usually.
Maybe someone knows how to change it?Some patch/mods or client upgrade?
Will be very thankfull for help!

Prob the server creator made them do that. Why not post on that servers forums as it might shed some light
