What is broken is the page update feature to register new edits and changes on flow pages. So, when you see an error message, assume it made your proposed edit (open a copy of the current window to check) just fine.
The page update feature, while working well on submitting pure text, how the base MediaWiki hooks interact with Flow got messed up when we updated to MW 1.37, so the Flow guys need to make sure they rename their own hooks so they sync to the page update feature of MediaWiki core. Apparently, they noticed the issues and are currently working on them according to the Phabricator reports.
Can confirm - it makes actually replying to threads and starting new ones an incredible pain, though.
