I've played Naev a few times, it's a good game.
I note that the Jumpgate from Aneel Azi to Tormulex is not visible (cannot be discovered) and cannot be autonaved through. The gate from Tormulex to Aneel Azi is visible and can be used. Since the jump line on the map is blue, I suppose both ends are supposed to be visible and this is a bug.
Cheers.
