It had an error that said 'Stardock needs to approve' so I ignored this whole ship printing excercise until a few nights ago when i tried again......
This time I registered an account and exported the ship to local and updated manually and its working fine (but a 89.99 sticker price for my battleship is a bit much for me)
I will try to upload directly from game tonight and see if I see a the approval status again
Honestly I don't think this is a game problem... My guess is a registration issue on their side which they probably fixed
