Short description of error
If you have these passes turned on, save and reload the file, they will appear turned off: Diffuse color, Subsurface color, Emission, and Normal
This can mess up your renders if you're using them in compositing and forget to manually turn them on each time you open the file.
Exact steps for others to reproduce the error
Open this file and you can already see the four passes are turned off despite me having turned on all of them and saved it. Turn them on again, save the file, and reopen, and they will appear turned off
