[Enhancement] Fog Of War Issues

Version 0.8 fheroes2_windows_x64_SDL2
Map: 0Test13.MP2
Save: 0_Test_13_0003.sav

Load 0_Test_13_0003.sav.
This is how the map appears when the save is loaded.



The hero's viewing area located to the south (red polygon) is correctly revealed.
For the three heroes located to the north, the viewing areas present defects, the squares circled in red should have been revealed (compare with the red polygon at the bottom).
This flaw is already present in the original game.



Now look at the boats.
In the red circles, there are areas of fog of war with a thickness of only one square.
I think when that happens, those squares should be revealed.
This would avoid having unsightly areas as in the red circles.



Back to the heroes.
There is a column of fog of war, one square thick, which separates the two heroes to the north.
As you can see, the default path of the hero located in the west bypasses the fog of war to join the hero in the east.



By moving the hero from the west one step to the east, the column of fog of war would be removed and the hero could join the hero from the east without making a detour.
Again, I think when the thickness of the squares of the fog of war is only one square, the squares should be revealed.
In this case, all squares surrounded by the red circle should be revealed.

Oh, it's a very curious issue regarding black fog... Could you, please, make a new issue in a special thread at https://github.com/ihhub/fheroes2 ? That's would be interesting, what our developer team can say about it...
But in my point of view - fog sickness in just a 1 square (world map cell) is ok despite it looks sometimes weird, but can make player's life more complicated, which is highly appreciated by me.
The only thing i want from the fog - is that it should be always created following the same principles.

Okay, I'll post it on the official issue thread.
