There are 54 countries in Africa - she could have chosen one. She's being lazy. Most of the time in the media locations on the continent aren't very specific (it's either "somewhere of the coast of east Africa" or some other generic place lol) and I don't understand why. It could have been a school in Tunisia or South Africa. We are a continent with many races, tribes, cultures, dialects/languages (not saying you don't know this) and it would be nice to see us depicted that way and not under a giant "African" umbrella.
"Mountains of the Moon, is a mountain range of eastern Equatorial Africa, located on the border between Uganda and the Democratic Republic of the Congo." they are also known as the Rwenzori Mountains. If intentional that is plenty enough specific.
