Hitvertx seems to be working fine in the first 6.4 release, but appears to be broken in 6.404.

I have read all of the forum posts, and also about the changes to c_trace in the buglist, and still am showing an error. Included please find hitvertex.zip. This is the most basic level, with only the necissary code to shoot and move.

If you run this under the original 6.4 version, when you move around (mouse and 'W' key) and shoot(Ctrl), you will see a small sphere at the hit point on both the model and the walls. If you shoot at the model, you will also see a red cylander appear at the vertex closest to the hitpoint.

This is all behaving well. If you upgrade to 6.404, the red cylander doesn't do what it is supposed to, and doesn't appear as expected.

Notes: If built under 6.404, if you shoot the head neck area, it will kind of work, but below this not. In 6.4, it works 100%, except for a strange area around the naval, which returns a vertex on the arm??
