Regarding this bug, one UI improvement I would highly suggest is to have the “Save Changes” button go into a different state after you click it. Whether it say “Saving…” or “Submitting…”, anything would be better than for the button to keep the same text as before I pushed it. There have been a couple of times already where I’ve gone away from the page because the button state stays the same, and it completely jumbles up the order of blocks when using Flexible Content.
