I have a set of points representing the nodes making up a polygon from a city-border. These points are projected in RD New EPSG:28992 (The Netherlands). I want to convert these coordinates to Lat Lon. I have tried to save the layer as a new layer with the WGS:84 EPSG:4326 projection and opened this new layer in a new project with the same CRS. However, this either shows a completely warped view of the points in a wrong place or it simply shows nothing.
Am I missing something obvious here? I am not new to QGIS and have done this trick with other CRS's lots of other times.
