Comment (by coreyw):

 @joemcgill It doesn't appear that resetting the globals would help. It
 seems that calls to `get_stylesheet_directory()` return an invalid path if
 called before a certain point (when the theme is setup perhaps).

 So, when ACF calls it during it's setup (`plugins_loaded` or similar),
 `get_stylesheet_directory()` returns the default theme path (`wp-
 content/themes/whatever`), but any call to that function during
 `after_setup_theme` returns the correct path (`custom-
 directory/whatever`).

 So this could be the fault of ACF calling the function too early (I've
 opened a ticket with them to investigate), but there is no mention of this
 being an issue on the
 [https://developer.wordpress.org/reference/functions/get_stylesheet_directory/
 docs page]. Or, WordPress should be handling this better and not returning
 an invalid path.
