there is a known issue in the save/open actions. hopefully it will be fixed in the next release meanwhile you can save the script and run the it every time you want to reload the model.

Unfortunately, with the new version, I get an error message now instead, when I save a script and try to reload it. I am able to load your tutorial script though. Very strange.

please attach your script so I can recreate the issue.

Thank you

thanks for the file, yes it seems there is a bug in save script action that cause all the command lines exported as single line. I'll take a look at this and address it in the next release.
