Been working for more than a week on a ship. I log on each day and do a little bit in the shipyard. But today I can't load it any more. The message I get is:
For what is worth, last time I quit the game I (unknowingly) quit from the testing area. So today when I loaded it up I was still in the testing sector. And my ship was there. I exited the testing sector, went back to the shipyard, and then couldn't ever open my design again.
Any other design loads fine on the shipyard...
