@carlbtmn As I recall the shortcode hack worked… BUT… I think (not certain) that hack stopped working after the WP 6.2.1 security patch for an Unauthenticated Shortcode Execution… and I’m not clear if 6.2.2 restored it or left it still broken.
Anyway, I’d say this is still open, and re-read tat GitHub issue for options to try.
I assume this is the same bug, but for me I have a custom taxonomy on my pages. When I select one/all the terms and save a new term is created based on the term_id. ie. I know have a bunch of terms like 87, 88, 89…
Save/load is turned on. Saving to $term_object or $term_id makes no difference.
Reverting to 4.1.8 fixed the problem for me.
