After the latest update the needles of the gauges in the GP38-2 from the Sandpatch route are turned black and barely visible.
No I don't think so, the needles should be red and white like the SD40-2 or UP GP38-2. Bot skins YN2 and YN3b are bugged after the patch. The amp meter needle is even partly white and black. So there is something wrong with the textures.
