didn't know it could be a loading issue , later i saw another guy and it was alright.So its been working 100% for me then :).
EDIT:Hm just saw another guy with 60% version of that mount and it was also with no texture. Its 99.9% also a loading error that but there is obviously some problem with those sabers cuz they are the only mount i've seen missing textures on.Even if a re-log fixes it its happening very often with only that mount so i guess its worth reporting it to the maker of this mod.
