Hi Jonathan,

Ive just checked the original URL (json file) for the London dataset that I shared with you… and the two thumbnails (Hillingdon and Lambeth) are missing but the boundaries still appear on the map.

Andee at Turks has kindly reconstructed the json file today to double check my work and the two thumbnails still aren’t working.

Can you confirm that the bugfix was applied, and if it was,  can you have another look at why the two thumbnails still aren’t working?

Many thanks, Mark
