I have two polygon shapefiles. It says in the information properties that the CRS IS EPSG 4326 and the other one says the CRS is a custom one (I put this custom one). Since these are shapefiles, shouldn't it not matter. The project CRS is the custom one, so in that sense its the same.
The issue is that I cannot convert the one with EPSG 4326 into the custom CRS since the polygons all disappear on the map. the way I changed it on a shape file is right clicking on the layer and and then it says layer CRS, I changed that to the custom one but it disappears. So I put it back to the EPSG 4326.
Is it fine if I just leave it as it is, I think it doesn't make a difference. I need to do this since I have to join attributes by location on these shapefiles. From the image they look the same anyways?
