top: export / bottom: original.
For some unknown reason, sometimes, when I export only a part of map, the map is not always exactly same as the original.
In that case, the white forest at nr23 disappeared. But my guess is that because the marshes symbol has been partially cut (west of nr16), it turned like every holes of that marshes disappeared (like the small hill, west of nr13, which should be also white).
@TwinPeaks I have nothing to show, to anyone, noooothing...
