Hi Elliot,
Unfortunately your suggested solution (hook into update_value before core update_value) CANNOT WORK.
Core acf/update_value is action, not filter, So, I may hook but cannot change anything.
_function.php line 26:
add_action(‘acf/update_value’, array($this, ‘update_value’), 5, 3);
You call acf/update_value as filter but later, from inside core acf/update value, AFTER stripslashes_deep.
So there is completely no way to fix this issue without editing your code.
Marek.
