when I go to Properties editor > Render > and click "Animate", it's rendering another scene... from a separate .blend file... that isn't open. I tried closing all instances of Blender, I tried searching online (most resulting in references to the "Blender is rendering an older version my project" thread on this site) and I tried playing around with the settings. There is nothing that I can see in the Video Sequence Editor. I have un-checked Compositing & Sequencer under Properties editor > Post Processing. I have tinkered around with settings and I just have no clue what's causing this issue. I'm still very new to Blender so this is something obvious, please forgive me.
