I remember reading in one of the update notes that Goronado's outfit had been fixed so it would now show our pirate's colors. After that update was applied, I checked with my only pirate who had Goronado, and they had not changed - still sort of red and brown. I figured maybe it had not changed since because I had him before the update.
But last night another one of my pirates became a Lord of the Apes, and I recruited Goronado for her and was pleased to see his pants were in her colors (pink with black stripes - very fetching!).... but when I promoted him, his pants went back to the generic colors. Will this issue be addressed in some future update, hopefully?
