Develop module has lost integrity on transfer of settings with the update. Now black point and white points are incorrectly mapped and this means images that had edits set in the previous version are not appearing the same in the new version appearing more grey due to loss of dynamic range. Furthermore this problem is not resolved by trying to apply the black and white points again resulting in exports that do not match previous exports! Adobe customer service appalling today! No one taking proper time and care with the problem and just saying there will be another update. I need to know when my work is critical time issue that was previously correct for printing and now all the images have been corrupted. A Disastrous update!!!
