Save might not be necessary as I didn't had played a single turn yet so I reproduced it using New Game with this settings :
- China 1890, Very small fleet size, Slight tech variation
- UK 1890, Super large fleet size, Slight tech variation
- Japan 1900, Medium fleet size, Slight tech variation ...

Regarding steps, it is quite easy, I just click the Load ship design button from the ship designer. Regarding the save file, I have several of them in my save folder, what is the extension of the one you need ?

Ok, I thought it was only DLC related and so I shouldn't have it.

The bad news is that if it is suppose to provide anything behind a File not found popup, it is not working

I can take one

Hello,

Thank you, the fix is working, I can load my design now !

I have a question though. I have a pop up with a Stock choice in my campaign but from my understanding this is DLC related, is it intended ?

Yes, they are created here without issue. If you need me to provide further data let me know.

In my case the Stock and Custom buttons lead to the same error message, probably because I don't have the DLC, juste the regular 1.01.38.

Hello,

I just finished my last campaign and so I updated the game to start the new one. I ran into the same issue in this mode too, is the fix still pending or did I missed something ?
