which are the main mistakes that are made about the Viceroyalty of Rio de La Plata? (same problem with the Alpine pass cession in history books hereNo problem, it's not your fault, that's more those who make base maps fault. I know that's a minor change but base maps should include it anyway, I mean after all base maps are mainly on accuracy of the borders and nothing more and if you make something wrong your mistake will reflect on those who use your maps for their works. People should document theirselves better before publishing base mapsAnd think, on the web you could even find base map of today Europe that still have pre WWII border between France and Italy!It was symbolic because it matched perfectly a natural border which was well established all along history, and marked since centuries (millennia actually) the righteous border between French and Italian regions.
