Solved NPCs modules.lua problem. Can only sell stackable items

[Thaian Citizen]

Hello everyone, I've been trying to fix this problem for some time now, I was searching the forum for different stuff but it all didnt work or links to modules.lua files were outdated...

I am using: The Forgotten Server - Edited By Cyko V8, version 0.3.6 - Edited By Cyko V8 (Crying Damson - Edited By Cyko V8)

My problem: I cannot sell single items through trade window. stackable items e.g. worms can be sold... non stackable items e.g. bow cant be sold, however this just affects the trade window, if I write sell bow, yes it can be sold, too.

Error print:

my modules.lua -> http://pastebin.com/QxGN3Qkc (the standard one that came with the distro)

Nevermind I have a working version of modules.lua now..

I took it from 8.6 FULL REAL MAP NPC PACK -> http://otland.net/threads/8-6-full-real-map-npc-pack.161374/
In case somebody gets the same error and needs to replace his modules.lua
