I checked the save file(s) but when I load save file 2 (in Woodhaven, raining) and go to the chess map, everything seems to work. Tried to but couldn't activate the square that the queen is on as the bug mentioned in the post you quoted. Did you hover the queen, press confirm and lit up the square? Every puzzle there's only one square activateable at a time, but this is intented as there's only one correct move in a chess puzzle. Helpful people have already posted the solutions for each puzzle.
