this one has that same dark look like your version. Idk what to think.

With very light lightmaps, he looks like this (default light settings)

It's unlikely that another person baked them in just the same way as you did. So this is strange. But I have no proof other than that guy's preview image and the time of uploading, which isn't enough of course.
