My topic "Multiple 'When.ModuleParameterIsChanging' events?" was an incorrect assessment, but it did locate an issue within HG that I has been added to github (#80). That said, I can fix my order of operation issues by adding the parameters to the HG core code. I don't know if these properties would be ones you would want to include, but I think they could be valuable for others.
Attached is my ModuleParameter.cs variant for your consideration. I don't know how to use the pull/fork system in github, so I'm submitting my code here for you to consider.
