Hi Matt;
I think the Trigger does not fire because it needs a command to activate it. For this to work when a piece is moved you need to navigate to the Map in the Editor where the Piece is located and add a Command in the field I have circled below then use that command in either the Report Action or the Trigger depending what you are trying to do.
How do I assign points here? Give a boquet of flowers? This is exactly what I was looking for. I am working on a game that asks you to plot out sometimes 200 or more moves before the game start for your fleets so I built a plotter dot and as you drag it around it annotates the log so you can just copy paste that into the fleet information box. Works a treat!
