I've found out that only colonizable disabling of Aethiopia subcontinent works. When trying to completely disable the subcontinent by turning it uncolonizable nothing happens. I have tried starting the game over many times and got the same result. I've tried letting some game time pass instead of taking the relevant disable decisions on the first day but that didn't help. I can provide savegames if needed. Thank you for your time :)
