@George:
I have seen this a couple of times in your AUM code snippets but I have to disagree: The polygon flag is a bad choice for animated and/or moving entities.
As does the manual clearly state in the remarks section:
Only one of the objects involved in a collision should have a polygonal hull. Do not set this flag for moving objects or for animated models.
Afaik JCL once said that using the polygon flag on moving and/or animated models may cause unforeseeable results in collision detection and thus should only be used for static environment objects (not moved by c_move).
