Is the Esperia Glaive being actively worked on? The NPC version that we are flying right now is in a very sorry state indeed. There are some very unhappy Glaive owners right now.

Well, the whole game is being actively worked on. All the ships are being balanced and edited, and bugs with them are being fixed. If you have any issues with the Glaive, report them to the Issue Council and they'll be added for folks to look at.
