I haven't been especially active on Starmade for a while now, but just today after taking a look in one of my ships, I noticed a lighting bug that wasn't there before.

{F10930}
As you can see, in the hallway of my ship, the lighting blocks are spaced out along a straight line in the center. On either side, wedges are used to give the walls and ceiling a "beveled" look. But now, one entire side of those wedges are completely dark, not receiving any light from the adjacent light source, while the other side is. I know that in the pictures it's the right side which looks dark, but if you are facing forward in relation to the ship, it's actually wedges on the left side of the light source that appear bugged.
It's also worth showing what the hallway looked like before. This screenshot was taken July 26th 2016 when I uploaded my ship, but I'm not exactly sure what version was current at the time:

As you can see, the hallway was still pretty dark (by design), but you can still tell that on either side of the light source, wedge faces are being illuminated, as opposed to just one side now.
