Fix the lighting!

OK I've just seen the third creeper in as many days loitering suspiciously around the diamond and lapis in the dome >.< I've tried to light up the area all around, but I tried that before, I think there's a dark patch around the new station, i can't think where else they came form, unless they got through the short cut somehow?

Anyways, can someone with better lighting skills take a look?

Hmmm... Has that pillar been fixed yet? I believe that may be the problem.
