Quaternion.Lerp messing up after being deactived and then activated again

Hey everybody!

I have a gun script that automatically makes the gun face the camera. Everything runs fine, but when i reactivate again (after hours of narrowing down the problem), the lerp function goes haywire and makes the gun start rolling on the x axis when the player starts moving.

 //get our position
 transform.position = Vector3.Lerp(transform.position, GameObject.FindGameObjectWithTag(tagOfWeaponLocation).transform.position, 0.99f);
 //get our rotation if we're not firing the weapon
 if(GetComponent<WeaponFire>().beingFired == false)
 {
 
 transform.rotation = Quaternion.Lerp(transform.rotation, GameObject.FindGameObjectWithTag(tagOfCamera).camera.transform.rotation, 0.433f);
 Debug.Log(Quaternion.Lerp(transform.rotation, GameObject.FindGameObjectWithTag(tagOfCamera).camera.transform.rotation, 0.433f));
 }

Thanks for any insight/help, Nikita
