Many thanks Topo65
After so many years playing SH5, you solved my issue
First i had to name my journal by the sub hull number, and not capt name... other wise it’s not working!
Second, i need to access nav map by M instead of icon, to be able to plot supermark with pencil.
Then, as you told me, saving journal by dedicated buttons before exiting to main screen, seems to work better than by the window pupping after exiting to main screen.
Back into game after loading save, first thing i do is load manually the journal by dedicated buttons, and i can see all nav marks and supermarks
I would prefer seeing destroyed marks instead of nav marks though...
But as turn around, i could put a supermark with appropriate text for each destroyed ship! This way, they could load each time ... or change the supermark icon by the destroyed mark...
