Description: 

I have the "Glow in the Dahrk" mod installed. Windows glow at night as they should, but some non-windows are also glowing now: in Bal Oyra there is a shooting range near Ajahni. The stands of the shooting targets are glowing like windows at night.
I've tested during the day - it doesn't glow.
