I’m not sure what causes the crash since as far as I know all the frigates I have are legal designs. When in the ship designer if I click on load they names of the ships are frigates but if I select one and try to load it the game crashes. In the deployment screen they do not show up as deploy-able ships.
If they are no longer “legal” ships that’s fine but i doubt it causing the game to crash was intended
The two errors generated are shown in the pics below.
