It seems that the island [[Åland]], more than 1,500 km<sup>2</sup>, is missing on [https://maps.wikimedia.org/#9/60.1333/20.1640 the Wikimedia map] used by the Maplink template, see Map 1. Some roads and places are displayed when you zoom in, but the "layer" for land is completely missing, see Map 2. Compare this to [https://www.openstreetmap.org/search?query=%C3%85land#map=8/60.174/20.212 OpenStreetMap].
