Custom ships have so many bugs it drives me nuts. I've spent hours trying to design ships, moving .shipclass and .shipcfg files around, attempting to directly edit the files, and finally just wiping all custom ship files and saved games.
Stardock, here's what we need: The ability to design the *look* of a custom ship using structural components apart from equipment such as engines and save that ship template to be reused in future games. Some of us spend hours creating an appearance for our ships, but the equipment we place on those ships changes each game. Right now this is a HUGE pain in the ass to manage.
Some of you are thinking we can do this already, but no, you can't, because of bugs. In order to remove multiple pieces of equipment from a ship, I must save the ship between each removal, because if I don't the previously removed item magically reappears when I remove a 2nd item. Then, for each time I saved, a separate ship is listed in the military quick build window. I have 12 ships named Destroyer III, only one of which I should be seeing.
