So I built a ship in Creative mode due to the fact that I was having trouble expanding the design I'd been using for the first few sectors. This ship was quite a bit bigger, but after a bit of grinding I was able to afford it. Problem is, whenever I entered build mode and loaded it over my original ship, I can't use it. The FTL doesn't work (despite having two) and I can't make the ship itself actually do anything.
Does anyone know how to fix this? I really, really like what I came up with, but building it from scratch in the campaign will be a bit time-consuming.
