Need another perspective: Personal Shield enhancements, what's wrong here ?

I've several 4DC units I'm working on that can self enhance to have personal shields. For all intensive purposes in comparison with the FAF client UAL0101 (Aeon commanders scripts & bp) these units should be setup correctly. However, what I am seeing is that the units can perform the enhancement but upon completions throw the following error...

WARNING: Error running /lua/sim/tasks/EnhanceTask.lua script in CScriptObject at 1974e8f0: ...alliance\mods\4dfaf\units\ual0108\ual0108_script.lua(28): attempt to call method `CreatePersonalShield' (a nil value)
         stack traceback:

I've gone over this unit with a fine tooth comb, checking and rechecking the pathing and verifying the structure of the enhancement in comparison with the Aeon commanders UAL0101 (FAF Client version).

My unit path is /mods/4DFAF/units/ual0108....

Can anyone spot what i may be missing from the enhancement process to throw the error posted above?

Thanks in advance!

Forgot to add a copy of one of the units.

I don't see a CreatePersonalShield in FAF code, did you mean CreateShield?

@nomander I'm not calling it directly, the create enhancement is. Same as how the commander does when it enhances itself.

Also create shield from unit.lua contains the following...

    CreateShield = function(self, bpShield)
        -- Copy the shield template so we don't alter the blueprint table.
        local bpShield = table.deepcopy(bpShield)
        self:DestroyShield()

        if bpShield.PersonalShield then
            self.MyShield = PersonalShield(bpShield, self)
        elseif bpShield.AntiArtilleryShield then
            self.MyShield = AntiArtilleryShield(bpShield, self)
        elseif bpShield.PersonalBubble then
            self.MyShield = PersonalBubble(bpShield, self)
        elseif bpShield.TransportShield then
            self.MyShield = TransportShield(bpShield, self)
        else
            self.MyShield = Shield(bpShield, self)
        end

        self:SetFocusEntity(self.MyShield)
        self.Trash:Add(self.MyShield)
    end,

Thus when create shield is called, the type of shield is later chosen.

self:CreatePersonalShield(bp) is a function only in the Steam version. You have to use self:CreateShield(bp) in FAF.

It's working...
