The new global-scenery has 4 bad .ter files that control one of the texture variations for northern irregular cities (the texture appears as flat green terrain instead of city).
This problem will be automatically fixed soon by downloading v8.30 via the updater.

If you do not want to wait for the v8.30 update to be released then you can download the patch immediately and manually install it.

here is the link to download the patch and installation instructions:
