Estou com um Problema, o Grizzly Adams da a task normalmente quando você conversa com ele, porém sempre que ele responde da o seguinte erro.

Lua Script Error: [Npc interface]
data/npc/scripts/Grizzly Adams.lua:onCreatureSay
luaAddEvent(). Argument #5 is unsafe
stack traceback:
        [C]: in function 'addEvent'
        data/npc/lib/npcsystem/npchandler.lua:642: in function 'say'
        data/npc/scripts/Grizzly Adams.lua:183: in function 'callback'
        data/npc/lib/npcsystem/npchandler.lua:430: in function 'onCreatureSay'
        data/npc/scripts/Grizzly Adams.lua:10: in function <data/npc/scripts/Grizzly Adams.lua:10> 

 

 

Além desse erro, eu fui pedir a task e goblin, e também me foi adicionada "Edron City - Elite Hunting: Goblins" Além da "Paw and Fur: Goblin".

Não sei o que fazer. Vou postar os scripts do Grizzly Adams e do npchandler.

Além desse erro, eu fui pedir a task e goblin, e também me foi adicionada "Edron City - Elite Hunting: Goblins" Além da "Paw and Fur: Goblin".

Não sei o que fazer. Vou postar os scripts do Grizzly Adams e do npchandler.
