Ferrarico tanks dont do any damage,how to fix this?

There may be quite a few reasons, i would check the player damage on the weapons themselves and also check if you have the scripts installed for ferrarico stuff. I would ideally check either the health of the dummy you were shooting or mabye get a friend to test the game and if the turret does not move for your friend then its probably a broken tank or script. Im not overly familiar with ferrarico stuff but i hope this helps in one way or another :)
