At the moment, I'm working on a copy of Bethesda's "DLC01dunDBChimeMasterSCRIPT" from Dawnguard (used in the http://www.uesp.net/wiki/Skyrim:Kinetic_Resonator#Kinetic_Resonator puzzle in http://www.uesp.net/wiki/Skyrim:Arkngthamz).

Anyway, I'm minding my own business, copy-pasting my code, making changes where necessary, when I reach this:

Event OnCellAttach()		; Set up all the chimes so that they know who the master is, using SetupChimes()	; ...also tell the centurion to be ghosted	if DoOnce == FALSE		SetupChimes(GetLinkedRef(LinkCustom01))		SetupChimes(GetLinkedRef(LinkCustom02))		SetupChimes(GetLinkedRef(LinkCustom03))		SetupChimes(GetLinkedRef(LinkCustom04))		SetupChimes(GetLinkedRef(LinkCustom05))		(GetLinkedRef() as Actor).SetGhost()		GetLinkedRef(LinkCustom06).BlockActivation()		GetLinkedRef(LinkCustom08).BlockActivation()		GetLinkedRef(LinkCustom09).BlockActivation()		DoOnce = TRUE	endifEndEvent

Now obviously, "SetupChimes" isn't an actual Papyrus function, and I haven't found a single reference to it in either the main DLC01dunDBChimeMasterSCRIPT script, or in DLC01dunDBChimeSCRIPT, which are the two scripts that control the tonal lock puzzle.

So unsurprisingly, when I try to save my version of the code (I removed the "(GetLinkedRef() as Actor).SetGhost()" line from mine, and I'm using renamed Properties/keywords, just in case I mess anything up), and what do you know, it tells me the following...

And all I can say is... "well, of course that was going to happen".

So how did Bethesda actually get that to work? What am I missing? Anyone have any ideas?
