In multiplayer (tested on the test server) attempting to load a design in a shipyard results in a bugged 'ghost' design.
Upon hitting the 'Load' button the shipyard says "Loading design" then immediately switches to saying "unloading design" and the error notification "Error: Cannot unload design! No design loaded!" shows up.
After this, the shipyard status says that there's a real ship docked, and a design with the design overlay is visible in the physical shipyard, but the Order menu options for a loaded design do not become available.
After logging out and back in, this 'ghost' entity is no longer present.
