HI,
When I'm saving a session displaying 3D image stacks as surfaces into a csx file, I get this error:
TypeError: object of type 'SurfaceUpdaters' has no len()

However if I switch the displayed stacks as volume, then there is no error on save.
This is with the daily build 1.3.dev202109160803 (2021-09-16) on OSX Big Sur (Intel architecture).
Thanks,
