Most default h1 bitmaps are corrupted, sprouting at these pixalted black,white,purple, all this other shit and making it mess. It does it to the default cubemaps(which is why if you close some textures are fine but the cubmaps are not), and your rasterizer bitmap is screwed to hell.

Simple logic.

Also do what everybody else says, re-extract it or dont override some bitmaps if it isnt necessary.

Next time back up what you think is important.
