[Geomoose-users] Change projection

That's because you've set you display projection to something other than
EPSG:3857 (likely EPSG:25833?). It is NOT necessary to change the
display projection just to display your own data. If you want to use
standard basemap tiles like OSM, Google, etc, then you MUST use a
display projection of EPSG:3857.
