This mod doesn't add Shipyard Capacity to the buildings it modifies, it makes them give Naval Capacity.

the number of assembly yeard it give is more than mégashipyard

Gotcha, I'll publish my fork in a bit @TrueWolves.

I'm not interested in that change and I don't mind what you do with this. It was a tiny edit.

I'd be willing to make a fork of this mod that makes the change stated below if the mod author isn't interested in making the change, with his approval of course.

A thought, since 16 and 32 are both stronger than the building that gives all anchorages +2, why not make the "Assembly Yards" give +Shipyard capacity and/or 10/20% ship build speed? You are after all using them to build ships. Then a full-sized shipyard with both can not only make the biggest ships, but 8 at a time instead of 6.
