P: Spot removal removing brush stroke

Resolved by i4detail, starting a new thread to focus on just the problem and solution so that Adobe doesn't have to wade through the previous long thread. The problem has been reported by both Mac and Windows users. I tested on Windows, don't know if anyone has tested on a Mac. 

Bug:

• apply adjustment brush with Auto Mask on
• remove a spot anywhere on the image, does not have to be in the masked area
• an area of adjustment brush is undone 
• remove another spot (doesn't have to be a real spot) 
• a different area is undone or sometimes the lost area is redone 

Solution / go around:

• don't use Auto Mask 

Solution / probably less acceptable

• do all edits except spot removal
• export the image at full resolution, no sharpening, as a jpeg
• import the jpeg and remove spots 

Great work i4detail 

Note that this problem has been completely unpredictable on my machine, however I decided to test your observations. My result is slightly different in that only Auto Mask causes the problem. I can use the adjustment brush as many times as I want as long as Auto Mask is off and then, no problems with Spot Removal. 

I'm going to start a new thread with this resolution / problem so that it will be more obvious to Adobe. Giving you credit!

So, when I went to record the video, I noticed that a few things had to be true for it to do this all the time. 

1) I had to select auto mask. 

2) I had to have more than one effects brush in play. 

This doesn't mean that it didn't do it in other situations, but that in order to cause it to do it all the time, I had to make sure I was doing these two things. 

Here's the video I posted above....

Ah. I see you did a video, too.  

@Rick

Here's one better; I did a video.

@Derek Richbell It would be helpful if you can share more details for this issue. 

Is this issue reproducible with the image you shared in the video with the develop settings? If so please share the image with develop settings (xmp file) or export the image to a fresh catalog and share with us.

I attached samples earlier to show that it is working the other way for me, however I've since discovered that the problem on my system is completely random. Most of the time, it doesn't happen at all. My Lightroom is completely without any sort of mods, plug-ins, presets, etc.; straight out of the box from Adobe. 

Bill I find that's when the problem arises.  I have better luck if I do spot removal at the beginning of the development process.  Doing it AFTER local adjustments is when it spits the dummy out.

Trick, but not a resolution, use spot removal as the last step in the develop process while we wait for a fix from Adobe. 

The strange thing, is that the problem exists on one photo and then not on another. I've yet to find a pattern. 

I'm having the same issues. Windows based
