FWIW I'm using Lightroom 6.12 (macOS 10.12.6) and the map offline issue still persists. Sure hope it is eventually fixed as I do like the map module and miss the former functionality.

Thanks, this is helpful. I'm not sure why I see the shift as the images are rerendered in Develop. Note once this happens the alteration is carried over to the LIbrary previews.

This is the standard answer for explaining the change in appearance of images as they are opened in Lightroom but one of the aspects of this explanation that seems perplexing is that Lightroom takes, sometimes considerable, time generating previews when images are imported (and one can see subtle changes to the thumbnails as this happens).

It seems simplistic to suggest that Lightroom is ignoring all the previews previously generated and starting all over with the embedded jpeg. If so what is the point of generating previews on import? ... View more
