Duplicate project needs to render again?
I duplicated a project in order to make a new version with a few minor changes. When I did so, all the renders had the orange line on the timeline, so it started rendering everything. In fact it seems to be taking forever to render. It's been a few hours already. The project is about 20 minutes. Why does everything need to render again for a duplicate and why is it also taking so long to do so? I duplicated "project only" as I didn't want to duplicate material, but just the edit. Am I supposed to have done something else?
