When setting the WB of a smart preview (original placed in an external HDD and disconnected), the photo turns turns very greenish.

I have been able to reproduce for Sony A7III raw files with 2 specific lenses (with a different lens it works fine):
- Sigma 50mm F1.4 DG HSM Art 018.
- Sony FE 25-105mm F4 G OSS.

Steps:
1. Import Standard + Smart Previews.
2. Place original in external HDD.
3. Disconnect HDD.
4. Select photo and develop.
5. Set the WB (from menu or modify any slider).
6. It turns very greenish.
7. If the HDD is connected back, the photo turns OK.

    Hey Todd, tried again and again, no luck! Didn't happen on the windows and Mac 10.14 machines at all.. I tried with 8.3.1 and previous versions as well, with GPU on. I shall try to get a set of images where it can be replicated constantly and try again.

    I was having this problem only when my source files were connected for some reason. If I built a smart preview and disconnected it would be fine. That said, here are two solutions I found.

    1. Go into Preferences > Performance > Check Use Graphics Processor.
    Mine was unchecked and when I turned it back on, presto! For reference, my graphics processor is apparently a "Metal: NVIDIA GeForce GT 750M". I know Premiere Pro has been giving me some stupid pop up messages lately about incompatibility. Maybe it's related to that ̄\_(ツ)_/ ̄  
    2.My files were already DNG files, but I reconverted the DNG from itself and chose the LOSSY option. I know this isn't ideal cause you lose quality supposedly, but problem fixed. If option 1 works, stick with that.

    3. As I mentioned, I could also build smart previews, disconnect, then edit based just on the previews. Then, reconnect just to export.

    Wow, I'm so glad I found this thread. I thought I was the only one having this problem!

    Many images turn half green in develop module when changes are made. For some reason, the thumbnail in the upper left navigator panel updates correctly, but not the grid or the preview module.

    Source HDD is disconnected. Smart previews and 1:1 previews were built on import. a7riii raw files on 8.3.1 Mac OS. 

    Is there a fix on the way? Any eta?

    I'm at my wits end with this problem! It's one thing to have access to the drive where the files are being stored, but as has been mentioned by loads of other folks in this thread we're having to edit photographer's files remotely as professional editors and don't have access to the drive where the files are stored. This results in an ultimate abortion of the job because the problem starts randomly and seems to snowball, to an extent, as editing progresses. There are few things more embarrassing than trying to explain this to a client. I'm not seeing a lot of progress in this thread with solutions for the problem and it seems that the most helpful things have come from other users and not Adobe. I appreciate that there are Adobe employees here trying to reproduce the problem and start the long path of fixing the issue, but it has been over a year since this problem was acknowledged and at this point we feel a little bit like we're being held hostage as Lightroom is the only program with which our editing workflow works! Abandoning it for an alternative would result in a huge $ investment loss and we're desperate at this point. 

    Sincerely, 
    a distressed customer

    Thanks a lot for sharing the steps, I'll try this again and confirm if the issue happens with my windows machine as well.

    Just wanted to comment hoping to get more attention on this. Very frustrating. My Smart Preview workflow is useless and it's been a year.

    Sony a7iii raw files here as well.

    I'm also having this problem, with smart previews of RAW files shot on Sony a7iii, when the source images are offline. Let me know if there's anything I can provide to help nail down a repro case. Only certain images show the problem, but the problem persists with those particular images (rather than showing up intermittently).

    With the DSC03740.ARW file I can see a similar rendering using this simpler three-step procedure:

    1) Switch to the Library module and import the file with 'Build Smart Previews' selected in the Import module's right panel. DO NOT VIEW THE FILE THE DEVELOP MODULE.

    2) Using Windows Explorer rename the file with .HOLD extension (DSC00574.ARW.HOLD) or simply move it to a subfolder.

    3) Now switch to Develop module and the preview will immediately look like the below screenshot with no changes to the settings and the Library module flashes magenta and then looks correct.

    If you you can't duplicate the issue using the above three-steps please follow the six step procedure I posted in my reply above. This is necessary if you inadvertently switched to to the Develop module BEFORE the original file was removed.

    If the original file is removed BEFORE it has been viewed in the Develop module the Camera Cache is not properly updated. From my testing assigning the Green Label is NOT necessary to duplicate the issue.

    In a laptop workflow some users may import new image files into the LR catalog, assign Labels and ratings, etc., but not edit them in Develop module. They then remove the external drive to continue working and apply Develop edits. This will cause the issue to appear, but should be a perfectly acceptable editing workflow.

    Take a look also at this two screen shots of photo DSC03740:
     - The first one: Lib. module --> it looks green.
     - The second one: Dev. module --> lees green, but a contrasty mess. At this one, the preview at the upper left corner looks normal.
