Ship designer bug in campaign

The design of the ships that I modify or create will change, after save, for the first modified ship that I made. Only their appearance change not the stats.

It affects every ship regardless of their hull size.

It doesn't matter if I use a ship in the shipyard list, a pre-made model or one created from scratch.

The weapons seem to be the cause, not the other equipements.

How to reproduce the bug everytime (in my case) :

- start a campaign mission, for exemple the tutorial, and open the designer.

- use the Sniper M1 design and save it (you don't even need to modify it, just be sure that there is at least one weapon attached).

- make a ship with at least one weapon (the model can be anything, even a constructor) and save, it will take the exact appearance of the modified Sniper M1.

It seems to happen only during the campaign missions.

Also if I check the game cache, after launching GC3, Steam finds two bad files, always the same : Core.bin and GC3.bin in the data folder. But if I check it again there is no bad file. It happens each time after launching the game, it doesn't matter if I play or quit immediately at the main menu.
