Here's a map I just made of 1914 because there's a lack of historical maps in M-BAM. Let me know of any errors in the map, and I might do second-level subdivisions at a later point.
Alright, it's a great start, but here's some feedback
-Guatemala wasn't claiming any of Belize yet, and I
think the Venezuela-Guyana conflict also reignited later
-The Costa-Rica Panama border was disputed
-The Peru-Ecuador-Colombia border area was a good deal different and much of it was disputed
-Chaco was disputed between Paraguay and Bolivia
-San Marino and Neutral Moresnet are missing
-The Beda Emirate in Yemen was independent at this time
-Fujairah had broken off from Sharjah but not yet joined the Trucial States
-Kuwait's border wasn't defined yet
-Arabia should be split into Anizzah, Hai'l, Nejd, and Najran (and maybe Upper Asir, IIRC)
-The Madha/Nawha exclaves aren't there yet, that region is disputed between Muscat-Oman and the Trucial States, and the Buraimi Oasis is an Omani/Abu Dhabi comdominium
-Darfur is independent, but as a vassal of Anglo-Egyptian Sudan
-Aussa and Jimma aren't incorporated into Ethiopia yet
-Hobyo and Majeerteen are seperate from Italian Somaliland
-I think Burundi wasn't incorporated into GEA yet
-Sikkim is seperate from British India, its status was more like that of Bhutan
-Bhutan has a few exclaves in Tibet
-Tibet, Mongolia, and Tuva/Uriankhai are all de facto independent from China
-Sarawak is independent
those are all the things I can see that are missing
