Operating system: Windows 7
2.80-1fa527bf, Blender2.8, 2018-12-05 (no render other scene in the compotision nodes)
No different scene is rendered if it is set in the nodes composer, and if it is manually rendered it is not updated when changing the frame.
If you open the file with blender 2.8 this error appears, but if you open it with 2.79 it is rendered correctly.
Steps: Open Blender file and press F12
Thank you a lot for your great work!
