Rendering inconsistent
On the Deliver page, I queued up two identical renderings of the full timeline, and pressed 'Render All'... the files that resulted were not identical (different file size). That seems surprising. Even with "use cache", I wouldn't expect that any new caching occurred during the back-to-back rendering (my observation has been that even sitting on the Deliver page stops ongoing fusion cache updates that are incomplete when viewed on the Edit page).
