Siege weapon campaign movement

[Garnier]

In descr_campaign_db.xml:
I changed:
<siege_movement_points_modifier float="0.75"/> <!-- movement points modifier for siege units -->
To:
<siege_movement_points_modifier float="1.0"/> <!-- movement points modifier for siege units -->
n descr_cam
But in game it hasn't been affected.. Siege weapons still move slower than infantry.

I made sure I have the IO switch on, and I changed the file in the teutonic campaign, and I know I'm playing the teutonic campaign..
