You sir just won my respect. Thanks a lot for this!
EDIT: I've found an incompatibility issue but i am not sure what causes it. The problem happens in battle; the word "Item" appears just in the Item command for actor in position 1 (despite wich character that is). The command itself appears for ALL actors, but the word "Item", just for the first one. The result is a blank square option for any actor who is not in position number 1.
This is the list of scripts that i am using (in order of placement, from the top):
QuoteZydragon's Simple Custom Menu System
Categorized Items Menu by Albertfish
Tons of Addons by Blizzard
Chaos Rage Limit System by Blizzard
Soul Force Combo System addon, also by Blizz
Teleportation System by Diagostimo

It is indeed the Chaos Rage System or the Soul Force Combo System. Maybe a combination of both. Thanks for your time
