v39.67.5 does not honour the Windows display setting: "Night Light" screen dimness/colour setting and reverts the display to the equivalent of nightLight-off . Bug occurs when the game launches, and prevails when closing the game. Windows shows the night light is ON when closing Zomboid, but must be toggled off/on again to return the screen to the intended dimness.
No mods, plain vanilla Steam version.
Once night light has been toggled off/on again, the game seems to honour the setting during subsequent launch/closing/tabing/anything of the game until after reboot.
I don't personally care when the game launches during play itself, but when closing the game and my Windows settings aren't returned the way they were I find it less than awesome...
