More ways InDesign wastes days
All of a sudden, InDesign has decided to repaginate a non-open file after every edit to the document that IS open. This takes several seconds of modal dialog.
Worse, however, is it adding page after empty page to my currently open document as I adjust the spacing on ONE page of it. Also, an unknown number of pages' worth of text has now disappeared from view entirely.
And I can find no way to reliably prevent InDesign from allowing spreads to go beyond two pages. I NEVER, NEVER, NEVER WANT THIS. I have experimented with every combination of allowing document and spreads to shuffle, and nothing prevents this behavior reliably. You also can't move the erroneously-positioned added pages to the correct side, again regardless of how you set the shuffling options.
So fed up with this mess.

If you add a page manually, you can sometimes get it on the correct side, but it's not connected.
