I'm new to QGIS. Recently, I had my first experience of having to draw a circle. This is in a Geopackage layer using the 'Add Circle' option from the Edit menu, only whenever I go to draw it, it ends up...not circular.
Circle preview: Circle drawn: Somebody else had a similar problem, see here: QGIS3 Shape Digitizing Circles is Drawing Improperly . Setting my coordinates to EPSG:3721 does allow me to draw a proper circle, but when I switch back to EPSG:32230 it's an oval (and I'm not sure how well EPSQ:3271 works for local-scale mapping in Scotland...). Is there any way around this that doesn't involve changing projections?
