Yes, that's what the game says when I remove ONE province from Spain. I have created Morocco, and the game loads up normally (I have to press "ignore" to every province owned by Spain and Morocco, though), but when I try to remove these provinces from Spain (already owned by Morocco), the game crashes and says "Scenario files had errors". Why? I have checked it through carefully, and I am 100% sure it is caused by the removal of the province's id from the Spain.inc file. Any ideas?
