Spikey model

[DECOY]

I am learning to use Milkshape by remodelling the front of a ghost.
Exporting the obj file from HMT and editing it in Milkshape is no problem.
The model imports back into HMT ok, as I am careful not to change the
total numbers of vertices or indices.
However.... when I view the model in the game, or re-export it from
HMT, it has two long spikes sticking out the front???

Any help??

did you like....edit the fp model and is the model only a part of the vehicle?

There are 8 models of the ghost and I applied the same edit to all of
them. (Each model is also comprised of three groups.) No fp model as such. I have rewelded the joints after editing and they all looked ok.
The models loaded back in through HMT no problem. But ingame they
have 2 vertices out of place. If I export the models again and correct
them, once I reload them into HMT, the spikes return.

EDIT* Can anyone confirm whether its possible to reduce the size of a
model? My remodelling produces a model marginally smaller than the
original. If I scale the finished model back up to its approx original mass,
the spikes a no longer visible.

Am I on the right track here?????

Maybe if you took a vertice from the middle and moved it to the outside, things would stick out like that
