Lua Problems skullcheck.lua and idle.lua!

[shurlie]

Ive been getting these errors when I kill a monster, just added Svargrond arena to my map.. So my problem is that I can kill the first monster, but not the second one, not even attack it, or any other monster!

Im using:
OTX Server Version: 1.3.1 (Moon Princess Edition)
A server developed by Martyx, iMadison & Kazbin
Based Version on: The Forgotten Server Version: 0.3.6.1 (Crying Damson)

[Error - Creaturescript Interface]

Description:
