Is anyone else not able to design or upgrade battleships because of a "missing module" (the heavy cannons). I have the technology and even started with battleships that have the part, but can't design or upgrade.

Did you add engine, armor, and weapons? Otherwise it will just say missing module
And which ship model is this?

I added everything I was able to add on the battle ship class. Every ship part except the heavy cannon module shows up just like on all the other ships. Even if I press auto, that piece will still not auto fill in.

add me on steam
