public_user_custom_fields in the admin panel, right? Not some setting elsewhere?
I was actually developing against our staging server which rebuilds the docker every time so I’m certain it was restarted (and then some). I’ll look at the JSON request this weekend and see if I can pin this down.
Wouldn’t this cause an N+1 query? Is there any solid documentation on the whole custom field system somewhere? I didn’t realize you could register the custom field type or append to serialized_current_user_fields
