I'm running into a bug when I have Post Type Switcher and Advanced Custom Fields enabled at the same time.
What's happening is that when I make updates to my custom fields with the ACF plugin, the post_type field in the database mistakenly gets set to "post" when it should be "acf".
This makes the custom fields effectively disappear. They don't show up in the ACF menus. If I go into the database and change the post_type back to "acf" all is good.
If I disable Post Type Switcher, I don't have this problem.
Anybody else running into this?
