Sometimes when I first receive a cube, it is already marked as if I had completed it.
The yellow is what the AI usually colors in when the image loads. The orange is what I color in. When the image pops up though, it already has orange in the image. It seems like the cube has already been completed by someone. The orange is not just one section. It has many small pieces, so I could not have accidentally hit it or anything. I have had this problem three times now including twice tonight.
P.S. When I take screenshots, I have to press the shift, this causes the 2D color to disappear like normal. The red arrow is what would normally be showen in orange.
