Fluidity and functioning collision with NPCs, but not PC (using Havok Object)

[Cacame Awemedinade]

Somehow, bounciness and collision looks perfect on NPCs, but my character's breasts dont react to touch, and when running, my character's breasts vibrate and twitch occasionally. Im using 10-29 and the Havok Object for collision because im a lazy asshole. Is the havok object outdated or something?
