We found the issue that nearly every page is now broken after the v3.2.1 update of b13/container. (TYPO3 v12.4.26)
We got a lot of container elements that switched position now in the frontend. This happens without changing anything in the database or backend for the pages. So the backend view/sorting is "ok" but the frontend sorting is broken.
I'm trying to add information to this ticket as I find it. But currently this is the symptom I can confirm on different typo3 installations.
