The lores bumpmap for Mars is off by 180. It has 0 longitude at the edge instead of in the middle. (The alignment of the lores surface texture map is OK.) It's a little disconcerting to find mountains in the middle of Syrtis Major instead of Tharsis.
(It's also somewhat confusing for the bumpmaps to be named marsbump1k, but I consider that a low priority misfeature.)
