When using CLONE, Vassal does not report the action.
Map definition includes:
“Auto-report format for units created in this map” which works correctly when selecting a unit from the Game Piece Palette, but it fails to report when using CLONE.
I think most games use the “Report Action” linked to the Clone Ctrl+C to deal with this and it would probably cause more problems to fix it at this point…
However, for v4, consider if CLONE should trigger the map auto-report…
The Map Window documentation links this reporting only to drag-and-drop piece creation. I don’t think it’s accurate to imply there’s anything to “fix”, as it isn’t purported to work in the first place:
Auto-report format for units created in this map:
A Message Format that will be used to report pieces that are dragged to this map window directly from a Game Piece Palette: The properties mentioned in the previous two items may be referenced as appropriate.
Whether the concept of piece creation could be more broadly construed for the purpose of auto-reporting is another question–it could just as easily apply to the Place Marker or Replace with Other traits, among others.
