I am trying to import some geopackage files. Some are polygons,
and one is a points vector. The polygons import fine, but the
point vector fails with:
ERROR: Detected different projections of input layers. Input
layers must be
imported separately.
Then if I convert the gpkg to a shapefile, it works fine.
Any ideas what could be wrong? Here's the procedure, showing the
problem.
