Ship design are messed up in the shipyard,
but not during designing.
Some of the ships I build appear messed up after I saved them. During the building process in the ship designer everything looks just fine, but as soon as I hit the save button and try to look up my design in the shipyard I get an image that is very little like the ship I designed.

Whenever I try to upload it to the workshop I can only take a shot of the messed up design.
This started ever since the update to the 1.2 version of Galactic Civilizations 3.
I think someone over on the steam forums figured it is being caused by using parts the were created from combining other parts. He might be right as a second ship I made did not have any problems at all and had not used self created parts in that ship.
