The old mat file for some reason specified different overlay colors for the Armored Transport. All textures from the mat files have been repacked in the vanilla mat files so they all use the original colors.
In the story, the Tekagi Transport strike force mentions the Transport cargo containing gold, diamonds, and thousands of articacts. However, the diamonds were missing in the cargo hold. It also only contains 1.000 artifacts, not thousands. The cargo hold has been edited so it matches what has been said by the strike force.
The transparent parts on the inside looked a bit weird in space, as if some areas weren't transparent at all. This has been fixed by completely deleting any colors in the transparent parts.
