Deck Gun Problem
 

Hi... I'm a newbie modder and I like to make my own mod with my Imagination, I have a problem when my crew trying to man the deck gun it's work but it didn't firing at all to enemy ship and when iI try to look closer I found that the deck gun is shaking frequently and it's keep never firing a single round. What I want to make is a different Main Deck Gun in a single ship, anyone can help to fix this problem?
