Error: (FF0011BA): does not have 3d and cannot have an effect shader played on it.
stack:
[ (0005D608)].EffectShader.Play() - "<native>" Line ?
[ (FF0011BA)].dunGeirmundsBossDuplicates.OnLoad() - "dunGeirmundsBossDuplicates.psc" Line 20
I think it's because the script is
Event OnLoad()
;Prevent the player from pickpocketing from the duplicate.
Self.BlockActivation()
;Turn on the shader once the duplicate's 3D loads.
Utility.Wait(0.1)
Shader.play(self)
EndEvent
0.1 is probably too short a wait?
