P: Local Adjustment or Synced spot removal to a cropped copy not sampling from the same as in the or

@didier_chr_tien 
sorry, this was a sarcastic answer, highlighting that they take so long to release updates and when they do, often unimportant issues are in the fix list, but critical stuff remains broken for ages and even more serious bugs keep piling up on top of this mess.
There are so many issues with how this product is managed: dev. outsourcing, different teams for LR itself and main photo engine - ACR, QA, bugfix prioritization, hotfix scheduling and general approach to releases. list goes on and on. I've personally lost confidence in the company and software and just waiting for the closest feature-comparable replacement from competition...

I know this has been reported to Adobe in other posts but it seems they're just not listing (as per usual). So here goes again.

There is a bug with how LR Classic 10.3 handles copying and syncing adjustment brushes between frames if some of them have been rotated or cropped. Instead of copying the brushes relative to the original frame LR repositions them relative to the new crop / rotation. This is not how previous versions of LR have functioned and makes LR almost unusable for me. 

Adobe. Please, please, please fix this ASAP. This bug has already cost me hours of work.

I released the Copy Settings plugin, which correctly copies local adjustments, spot removals, transforms, and crops between photos. It also lets you define presets for which settings should be copied.  I'm hoping that Adobe will fix all the bugs with Copy/Synchronize Settings soon, but meanwhile, this plugin will get the job done.

V10.3 and no correction...

So no correction planned ?

Folks, forget this issue, now we finally have column-aligned icons in MacOS and send to Apple Mail works, this is so much more important than some stupid copy-sync stuff and other develop bugs... it was definitely worth the 3 months of waiting. It feels so refreshing to be heard and have those nasty issues fixed.

Hello John,

V10.3 and no correction 🙂

Idem for the brush etc...

I've written a memo analyzing the various problems with copying crops and local adjustments and providing a straightforward method for correcting them:

You may be right. Resampling is done (and makes sense) when you copy between different images. It does not make sense when you copy between virtual copies and the master image.

"When you sync a spot removal, Lightroom will resample."

I don't think this accounts for the behavior observed here. Copying a spot-removal clone from a virtual copy to an original, with no cropping, usually shifts the location of the clone source.  The shift is the same each time you do the copy, ruling out the possibility that the algorithm for choosing the source is stochastic (using randomness).

LR 10.2 tried to fix a longstanding bug with copying local adjustments between photos with different orientations (rotation), e.g. from a photo rotated in-camera to a TIFF created from that photo in Photoshop.  This worked for a couple of the adjustment tools but not others, and it introduced more bugs to common use cases that are reported elsewhere.

Internally, each adjustment tool represents the coordinates of the adjustment slightly differently, and I'd bet that the attempted bug fix in 10.2 didn't apply the right "fix" to the coordinates of the spot-removal clone source.  (I'm intimately familiar from the internal representations of the adjustment tools, incorporating them into my Any Filter and Any Crop plugins.)
