I created several related blocks on a master page. The blocks don't auto-continue; they're not master blocks. I then initialize them and filled them with text. Then I group them with other elements. Then I no longer needed them, so I tried deleting the blocks. But InDesign wouldn't allow it, as it thought I needed to add pages. I deleted the entire contents of the text blocks. But InDesign still tried to add the page, even though there was no content in the blocks. The last block in the chain link always had a continuation icon, but in reality this block did not have a subsequent block.The block-by-block connection ended up going nowhere. After ungrouping, I started deleting the blocks one by one, and each time the last one in the chain ended up with a connection that led nowhere.
