When I edit TIFFs, for instance using the brush, Lightroom periodically reloads the picture on its own and my editing work is gone. This is very annoying. Does anyone have a solution. I already had this problem with LR4, now it's still there in LR6!
Does this only happen with TIFF files or also raw and JPEG? What settings are you applying with the Adjustment Brush? When the image "reloads" are other Develop module adjustments reset (0) such as the Tone panel?
The next time this happens copy and paste the History panel contents here:
