Item Spawning & Using Problem

[Pigger]

Hello again, another problem it seems. This relatively simple (I think) trigger is giving me issues.

Cunning Disguise
    Events
        Unit - A unit Starts the effect of an ability
    Conditions
        (Ability being cast) Equal to Cunning Disguise 
    Actions
        Set DisguisePos = (Position of Caster1)
        Unit - Create 1 Dummy for (Owner of Caster1) at DisguisePos facing Default building facing degrees
        Set CunningDummy = (Last created unit)
        Hero - Create disguise and give it to CunningDummy
        Hero - Order CunningDummy to use (Item carried by CunningDummy of type disguise) on Caster1
        Custom script:   call RemoveLocation(udg_DisguisePos)
        Unit - Add a 2.00 second Generic expiration timer to CunningDummy

What is supposed to happen:

Unit casts spell, Dummy unit spawns on caster's position, Dummy unit (which has a hero inventory) is given a created items, Dummy unit uses the item on casting unit. Fin.

The Problem:

When the spell is cast, the item is created in the middle of the map...

Attempt making the dummy unit a different unit. Then, if it works, try giving the unit a size of 0(with triggers), and make it perm invis. Like I have said, I suck with ability triggers. >.<

It's wierd though, because the trigger works perfectly on another map of mine :S

o.o Did you actually copy it from map to map? And they use the same unit?
If you copied it, you should try to use the exact same units/variables. If it still doesn't work, your map has to be corrupted.. o.o I think.. >.<
