some of my model is invisible

[Tauer]

Hey, I just finished creating my own Gul'Dan model. It looks great in the WC3 viewer, but when I launch the game, it looks very strange:

I'm sure it has something to do with the geoset, I just can't figure out how to fix it... If you could help me, it would be great
I've uploaded the files if you should need them.

Please?

Here it is:

The problem was a messed up geoset animation.
