I think tomorrow will have new update.
Have clean up & deleted all useless and left over TGAs (quite many).
Have adjusted environment (overcast & overcast rainy) for better visibility on conning deck. It was still too dark, and I believe you can see crew man at 2 meters from you even when overcast and/or rain at night
Have corrected the MX04B guns position (as Fitzcarraldo noticed)
Others minors adjustments.
I think no need to restart career; it should be saves compatible in bunker …
