Difficulty running my plugin from the command line

Hi,

A while ago I created a plugin called AutoBeam. I have recently started using it again.

When I now try to run the plugin from the command line, for instance like this:
mscore -p autobeam.qml Walking_Backwards.xml -o Walking_Backwards.pdf

The plugin is executed when musescore is run, as the debugging logs are printed. However the plugin does not make changes to the music. The plugin works fine when it is run from the new "plugin creator" within musescore.

Do you have any idea why it is not working the same from the command line?

Thanks for your help!
