If you add 8 bytes, you have to del 8 bytes somewhere in the header to keep the pointed things right placed (this is the reason why i obtained yesterday vertices with only 1 data of the 3 needed)
I tried this, first deleting 8 times "00" at 0x48, and adding 8 times "00" at 0x2C
and i obtained a "better" but bad list of vertices
Code:
<more v up>

<more vn down>
now it has 3 coords, but crashes when building faces.
tried again "moving" (adding/deleting way) the "boundingtriangles/vert/normals" to the TBC locations and continues crashing
