FIXED:[2018.41570] - Frozen SOPs lose groups on project load

Steps to reproduce:

  • Create a SOP with some primitives (e.g. a Sphere SOP in polygon mode)
  • Feed it into a Group SOP and create a group out of some portion of the primitives
  • Feed that into a Null SOP and lock it
  • Save the project, exit, and reopen it

The Startup Errors dialog contains:

A popup dialog is shown with the same message.

The locked SOP will contain the correct geometry but no groups.

other than that 41570 is amazing. so much new stuff to explore!

Thanks, we can reproduce it here and will have a fix shortly!
