Galera estou com um problema no server, jogador vai vender umas daquelas esmeraldas não da pra vender mais o npc tem lá para comprar.

 

Outra caisa se vc tem 2 demon shield 1 esta na bag e a outra está equipada, se vender para o npc a que está sobrando á que está equipada somi também o npc compra as 2 mesmo você escolhendo para vender 1, o dinheiro recebe mais não é isso que eu quero, se escolhe vender 1 é para vender só uma.

No caso da esmeralda eu não entendi muito bem o que você quis dizer. 

 

Provavelmente pode ser algum erro com sua npclib.

[IagoNp 50]

Bom maxwellden não sei configurar mais da uma olhada ver se você encontra o erro.

 

Tipo os itens você tem 4 war hammer vai vender no npc só aparece para vender 1 mais quando vende, todos os 4 são vendidos, o dinheiro é ganho como se tivesse vendido 4 mais você só queria vender 1 ai é mesma coisa com equipes e os demais você tem 3 demon helmet você usa 1 e quer vender os outros 2 ai vai no npc lá aparece como se tivesse só 1 para vender mais quando vende, os 3 são vendido do mesmo jeito.

 

Bom é isso vou postar os itens do npclib para você olhar se puder.
