Unknown forces being added to ragdoll

I'm using ragdoll physics in place of death animations for enemies in my game. However, even when I'm not applying forces, forces are seemingly being applied to the various rigidbodies on the enemy game object.

I was initally applying a force to all rigidbodies on the various limbs when the enemy's health reaches 0. However, I noticed that even when I removed the aforementioned code, the ragdoll would still fly all over the place whenever I shot the enemy.

There's nothing special about the shooting. I'm just raycasting. I can't think of any reason why any forces are being applied from a raycast. I've searched the entire solution to see if I've applied forces elsewhere.

The relevant scripts are below. Can anyone help me? Have I missed something obvious?

OK, I've figured out the issue. The particle effect was applying a force. When I disabled the particle effect, the enemy stopped responding to the shots.

However, I'm not sure what setting within the particle effect is causing the issue. The collision box is unchecked. Any ideas?

Nevermind. I've sorted it. There was an explosive force script added to the particle effect I'm using.
