This has happened to me 3-4 times in the past couple weeks. I will be editing the source of an email that I created in v2. When I click save, Marketo loses all of my updates from the revision I just made, as well as any revisions I made days, even weeks earlier. Has anyone found a resolution to this issue. I have actually started saving copies in an HTML editor so that when Marketo loses my revisions I can copy and paste in the updates it just lost.
