Model error with Council Ascendants

[srmalloy]

This only occurs with Council Ascendants carrying the big sonic weapons -- the ones with the big muzzle brake and the drum in front of the rear grip. When the Ascendants go into their defense state and become intangible, their weapon disappears -- except for the drum, which stays in position, floating in front of their right hand. Because this does not really affect anything -- the weapon returns to normal when their intangible period ends -- it shouldn't be a high priority fix.
