Sometimes when logging into the game (and getting much more often), the game is darker than it should be and there are no shadows, also cannot see flags (they appear all black).
Even when it's a sunny day in DayZ, it looks like a very overcast day.
Logging out/in doesn't seem to fix it, but closing the game completely does.
Experienced this on PS4 and PS5.
Seems to happen every time we get a server reset.
