Morri it looks like you colored the picture and uploaded it as the same filename, which overrides your old one. This happened to Annie too on her lioness jungle animation. I found out why and took care of it, but you'll have to edit your older one and upload the uncolored version to it if you still want it in your album =)
Sorry guys, its software in development which means there are gonna be bugs and errors along the way. Thats why its really important to tell me if even the slightest thing seems wrong. I don't notice everything
