Bug or feature ?- animated collision mesh.

I have created a test object, with a collision mesh, and ambient animation.

When firing my weapon at said mesh, collision works as expected.

When the player enters the objects collision influence area, it seems
T3D takes a snapshot of where the collision mesh is at that time,
and uses this then static collision mesh to calculate the player collision.

See vid:

Is this an expected feature ?

If this is an expected feature, could I request an option to set an
animated meshes collision (regarding the player) to be updated on a
per tick or frame bases, ie a check box 'animate collision for player'

I am sure there must be a reason that the collision is animated / tested
for weapon projectile collision, and not for player (bug or for performance)

Cheers,

Hewster
