Checklist of files to include

Anything else?

I suspect the problem is occurring when the project is saved in Orca. I create a project in Cura and save it, then open in in Orca I do not get the error. If I then resave the file in Orca I get the error when opening the file. Also of note, when I tried to open the Orca file in Cura to see if I get the error "There were no models in 2 trees.3mf."
