Changing the appearance of an animal can sometimes glitch out for yourself or for other players looking at the animal.
Sometimes when you switch the colors of an animal, it doesn't update on screen. Moving may help to update it on screen, and clicking on the edit animal icon will update the button too. Your animal may appear the same for other people too before you update it by moving.
Eye and pattern type can also fail to update. Sometimes, changing these do work, but they appear with the incorrect colors if you have changed the colors of them too.
Switching the pattern on patterned animals may also fail, and the pattern will show as unchanged until you update it.
Switching a legendary eagle's pattern type will sometimes glitch the colors of the original pattern onto the new pattern type. If you move, the animal on screen may fix itself, and if you click the edit animal button the icon may fix too.
