When the AI copilot created or edited a workflow for you, the change ran correctly behind the scenes — but the workflow editor could still show the old version after a refresh, making the edit look like it vanished. Worse, if you then made a manual change, the editor could save that stale version back over the AI's work.
The root cause was the AI writing to one copy of the workflow while the editor read from another. AI edits now update both in a single step, so what you see in the editor is always what actually runs. Any workflow that was previously affected heals itself the next time the AI touches it — no action needed on your end.
