Recently I made a new puppet state (The Armed Republic of Fila Eur) and after solving the 4 issues given at the beginning, I had noticed that the classification had somehow changed, making it so that instead of it being "The Armed Republic of Fila Eur", it was known as "The Jingoistic States of Fila Eur", meaning that I had somehow unlocked a secret classification.
Don't say that I'm lying. If you search Fila Eur, you will see that it only has a population of 5 million.
Anyway, the question is, has anyone else discovered any other secret nation classifications? If so, please let me know, as I'm really curious
