Issue fixed by adding featured image support to the custom post type, also seems to have been fixed with ACF V5.

Fixed it, trying to go for $location = get_field(‘location’); when I renamed my field map_location 😉
Just an update, I tried to echo out lng/lat and it shows “||” so these fields are not properly saved, would appreciate any help or advise.
