It seems that the French managed to hold onto a colony in South America, while this 'UK' managed to colonize the Malvinas before Rio de la Plata did. What's even more interesting is that La Plata lost 'Uruguay' and 'Paraguay', but has the majority of Patagonia. And the Andean part of Patagonia is called 'Chile' and has a significant chunk of Bolivarian Peru.
I find the borders in Europe even weirder. The Low Countries are split into two, Suomi is independent from Russia and seem to control a significant part of the Gulf of Suomi on both coasts, and either Arctic Denmark or Baltic Denmark have broken away.
