[Request] Solution to broken weapon textures

One thing I noticed, retexturing weapons, was that some weapons would screw up on one side no matter how you saved it/edited it/even if you -didn't- edit it, just ripped it and put it in a new UTX. This even happens with no alpha channels, though there'd be an added bonus of blackness. I can't figure out how to fix this at all, they just seem broken, but I rip them straight from the original hellbound texture utx (using l2viewutx) and put them in mine without editing them, how can that screw only a handful of weapons up?

Any ideas? Seems like some of the best weapon textures have this issue, whether they're wp_ori or sp.
