I finally portforwarded and got my cousin to join my game. He got on, and all the armor I was wearing and a few items appeared as blank white squares. I figured out it was because I dl'd newer sprites, and since he dl'd the Eclipse Stable from the forums, he didn't have the same sprites as I did, thus causing them to appear as white squares. The question I have is, if I download more sprites in the future, will they appear as white squares for everyone all the time? How can I prevent this?
