A small bugfix and performance patch. No gameplay changes; existing saves are compatible.
Performance
- Building roads and railways by dragging is smoother, especially over long distances.
- The New Settlement panel stays responsive as your network grows.
Fixes
- Drag-to-connect: clicking away from the road/rail chooser now closes it and clears the dashed line.
- Waterway drag no longer leaves a stray dashed line on the map.
