It is not possible to copy paste a simple mask to more than one image. LR asks whether it should replace or merge but which ever option is selected it does nothing.
Steps to reproduce
1. Open a catalog with several photos
2. On one photo create a linear mask over the whole image and add 25% moire.
3. Check the changes are made correctly.
4. press the copy button (bottom of left sidebar) and copy only the mask.
5. Select the other images and press paste. The "replace/merge" message will appear but whatever is selcted the mask will not paste to any of the other images.
6. Do the test again and only select one image and paste works.
Pasting a simple mask to several images does not work
MY TEST
In my case all photos were from the same camera and in the same file location. The mask was a linear mask of the whole screen to remove moire. No mater how many images were selected if it was above 1 then it didnt work and so 400 images have to be pasted to individually to correct the moire.
Using that latest windows version of LR classic 13.0.1 (just double checked that now).
ACTION
Adobe need to either fix the pasting of masks to several images or add a message to tell the user this is not permitted.
ADDITIONAL SUGGESTION
It would be good to have a global Moire slider within the detail tools and not just in the masks.
