I forget which tech it is, but once you research it you can build the Caretaker ship at your shipyards. It has a module called "Repair Bay" if I remember correctly, and it gives the fleet +2 repair per turn.
However in the ship designer, this "Repair Bay" module is nowhere to be found. So the player can never design their own fleet repair ships, they are forever stuck with the tiny base model Caretaker if they ever want to have any extra fleet repair. Unless they have a commander ship or some other special thingy that provides fleet repair.
Please add the "Repair Bay" to the list of components in the ship designer.
Happy Bug Squashing!
