If you look at image properties of the .gif files with gimp, all the H2 images are indexed color with 19 colors except that one. That one has only 18 colors, and it looks as if something has gone off the rails with the colors when generating the different rotations. The colors also look different for that rotation in gimp, but not green. I would guess that one rotation is a corrupt .gif file.
