We just upgraded to Confluence 6.0.3 today and I discovered that when editing an existing page, if you navigate away without publishing changes, it doesn't get logged in your drafts. It's only when creating a new page that you leave unpublished that it will go in to your drafts.
This is confusing for my users and is very unintuitive to have to remember where your different drafts are. If something is in 'draft' status, it should be in your drafts! Am I missing something?
