Texture Map placement correct in S4S, incorrect in game

Hello 

I would like some help troubleshooting this: I'm making some festive lights with a glow achieved through the use of an additive shader. 

The map for the glow shows up correctly in S4S (1st image)
But in-game, the map is tiled & off-centre (2nd image).

I've attached the pkg and blend files below.

TIA!
