Crash log

N/A

How do you make it happen again?

bug is most easily demonstrated with inverted light sources:

1. get a light source from Project Red: Illumination that isn't an illumar lamp (the full-block ones) and place it down in a dark area. observe that light is only produced for one tick. if the f3 screen is opened, the block light level can be seen to change briefly, then immediately go back to 0
