I just noticed my head on the site was grey, and when I went to check my body colors in the avatar editor, I noticed they had been reset to the default:
I have not changed them in a long time, and as my avatar on the devforums depicts my body colors were blue up until just recently. The most recent change to my avatar’s appearance was yesterday when I bought and equipped some of the Ninja animations, but I don’t believe that is the cause, as I tested them out in Play Solo and my avatar was blue still. I cannot reproduce the issue by unequipping the ninja animations and re-equipping them either. This is the first time this has ever happened to me, and I have since corrected my body colors.
