I was playing the story on base last night and swapped looks from my CAST model to the humanoid one which had yellow deuman tattoos, only to find the tattoo color had been reverted back to the default teal. I had already used a color change pass for this and as everyone knows how restrictive color changing is, this is an actual problem.
