The report below happened to earlier new designs too
So here i am trying to create a new ship, a large troop transport.
Instead of using the standard transport/cargo size template, i started a Large size template (picture 1). I started blance with a starter block. Overlook the poor quality design, i just did a quick create to show here.
The weird thing is that after i save the new design, in the design list the designs shows up with the stock corvette version and not my own design (picture 2).
This has happened aswell with 2 earlier combat designs, of which one is shown in picture 3 (you can see the difference in the feature list (like it should show beam weapons instead of missilepods)
