The Current flag of the Pacific is giant. Like really big so I decided to see if the big flag was for all regions. So I upload and changed some flags of a region a founded and founded that the flag size wouldn't increase. Then I founded a new region and saw that the flag was still not so big. Then I decided to download the flag of the Pacific and set it to be the flag of another region and the flag was giant. Then I edited said flag and re-uploaded it and the regional flag is giant. Check the region Puptopia.
Is this a bug, probs is.
