Hello,

Adding Korean translations of cities or regions is fine, but please avoid changing multiple places within the same upload.  If you edit names in Canada, South-America and India and upload them at once, it generates an unpleasant giant bounding box covering half of the planet.

Next time: one place = one upload, please.

Thanks in advance.
