Lights in the stone mine
 

As you can see in the attached image, there's some greyish-white lines in the conical light.

Yeah, I know what you're thinking, but somebody complained so...

I don't really like those lights anyhow. As far as lighting goes a mine should only have torches on the wall or lanterns near major mining spots and mining hats (worn).

I disabled the lights, they were laggy anyway if there are too many in one level. Maybe we replace them with some particle effects later on which don't look like that there is some big hohle in the mountain.

Those lights don't make any sense. O.o at least, shouldn't they be flipped vertically?

Yea, rofl, thats what I thought.
