Is it normal for some people to have pitch-black hair in fall? I noticed that Wakuu changed hair in summer to blue, so when I saw him with pitch-black hair in fall I thought it was cool, but his blue hair in summer also changed in his 2D picture, as his 3D model, but in Fall his hair is not Pitch-black in the 2D pic, just his 3D Model so I thought it was odd, and then a lot of "townies" got the same hair. Eleanor, Valentina, Antonio, Randy.
What can be causing this?
