I apologize if this bug has already been reported, but since I haven't seen any mention of it, I just wanted to highlight about a UI bug where the maintenance cost of ships are shown as zero in both the ship designer and the shipyard. Below is a link to a quick example showcasing this error in the ship designer. Regardless of what is on the ship, its final cost shows zero for maintenance.
