Can't tell why exactly your flag doesn't work, but I would suggest you upload the image to the wikia and use the link from there to update your nation's flag in the game. This also makes it easier to update the wiki page, and it's better as a long-term solution - since the link won't expire, it will be easier for future players to find out what the flag of Davostan was in the 4180s.
