Unpublishing a unit unpublishes what's inside
Topic C of History was published, with Lessons 3 and 4 and their Teach Books. It needs reworking, so Ben unpublished Topic C.
Unpublishing a unit unpublishes every row inside it too, in that language. They aren't just out of readers' reach: each one is now not published, and your tools list them when you unpublish. Publishing Topic C again later brings none of them back. Each one is published again on its own.
Try it: select Lesson 3 as editors see it, and look at its English version.
Lessons 3 and 4 and their rows are each marked “Not published”, though nobody unpublished them one by one. When Topic C is ready again, publish it together with the rows you want readers to have back, and leave out any that aren't ready.
