[Fixed - persists in 3.62] [old bug] fence construction

[Plotinus]

If you start constructing a fence when you are ready to drop, it places the initial fence on the map, but when you try to continue it after sleep, it demands more wooden stakes. you have to deconstruct it before you can continue. This is an old bug and was present in previous versions.



Also the grid lines show faintly on the ice, even with [MAP_GRID:NO].
