So, i noticed that the coat of arms and the circle of leaves on the Belize flag looks off-centered compared to the white circle. However, i'm not very sure if the white circle or the leaves-coat of arms combo is really correctly centered, but it seems that the white circle is mostly likely off-centered.
I've corrected this flag and it should be live on the server now. If you still see the old version, a hard refresh (usually ctrl+F5 or long-tap the refresh button) will update it.
