When I need to remove Topics pages and the associated links to watch the videos in the Community, because I roll out to EU and AP, I must unpublish both pages at the en blueprint and also at both the en_eu and en_ap regional blueprints (which to me look like live copies, on the list, but the folder is blueprint).
If they exist as translations anywhere, they need to be deleted there, also.

Yes... @gail_massari, the en_eu and en_ap regional blueprints ARE both live copies of the en master blueprint AND blueprints for their own respective live copies (e.g. en_gb (under en_eu) and en_au (under en_ap)).
