@crocobaura, the game does not allow you to have goaled events on holidays, because the UI for goaled events and the UI for holiday traditions are the same UI element, and the UI can't be shared by two things at once. You, literally, cannot hold a base game goaled event on a holiday. It won't let you. If you try, it falls back to the non-goaled version of the event.
That's why i asked...because I figure MWS events fall into that same category, but I don't know for sure. And MWS events have no "non-goaled" version to fall back to.
