I once got invaded by Argentina as Japan.Honestly even on Normal speed Brazil, Colombia, and Argentina wind up in wacky places. Think it's a combination of big starting armies, starting navies, and (usually) not being at war with any major civs. Ironically, I see a decent amount of time on the 1700 AD start the Second Wave of Colonialism starting from the just liberated South American colonies.
