Pitchypoy rigify issue

Using a character rigged with Pitchypoy Rigify in different scenes. Can't understand why when opening certain scenes the "rig layers" normally visible in the N panel disappear.

My "auto run scripts" in pref users is ON.

Any help?

Appending the rigged object to different scenes doesn't automatically include/run the rig_ui.py script. The script can then be located in the original .blend file's /Text folder.
You can also keep a local copy of the script by generating a new Rigify rig in an empty scene and saving it. Just be sure to change the rig_id in the script to match the rig you wish to generate a UI for before you run it... like this:
