I'm playing on PC with keyboard and mouse and have the camera zoomed out (+ all the way out) but after a while I notice that the camera is now closer to the character. Not as close as the game's default close camera (pressing -) but it is noticeable and I have to press + again to zoom out.
This happens every few minutes so it's annoying after a while, especially since the camera is so close in the first place and it affects the camera movement (it feels off).
