copying edit sequences into another sequence is swapping multicam shots

Not sure if it is related, but I was having issues with multicams being updated where 2 multicams exist with the same UUID (i.e. where project is duplicated and multicams then amended). THere's a workaround in my post:

Hi @Andrew C. Brinsmead -  That’s fantastic! We understand how frustrating it can be when the app isn’t working, so we truly appreciate your patience and efforts in troubleshooting.  We’re glad to hear you’re back up and running.  Please don’t hesitate to reach out if you encounter any other issues.

Thanks @jamieclarke  WE HAVE A WINNER!!!!!  (sorry for shouting! 😉 but I've had several weeks of severe pain with this - to the point where I was contemplating moving systems!!!).  I've started to use Premiere Pro with a completely refreshed / rebuilt user preferences folder (the 24.0 folder), and I've removed all the previous user preference folders, so far - very good! 

I'll have to keep testing this solution - but already I can do the exact kind of edit (sequence from one project in my source monitor into a sequence from another project in  my program monitor).  I've done a few test edits - and they've all worked as they should; I'll keep editing during the day & let you know how it goes.

This has also fixed another issue that I was having - when I adjusted a colour effect in the Lumetri panel (on a clip in my program timeline seqeunce), the video output (and video scopes) kept reverting back to the source monitor output - this is now fixed too!  Double points for you @jamieclarke 

PS: @Jarle Leirpoll  & @R Neil Haugen   thanks for your help - it looks like @jamieclarke  has found the answer!!! 

Thanks @jamieclarke  I'm trying that now; I've just replaced my user settings (although it's interesting that a lot of my previous settings have appeared (I think this was done automatically from my 23.0 settings folder, so I'm going to remove all of my previous user settings (going back to 12.0…) from the documents / adobe / Premiere Pro folder)

Hi Jarle, thanks, but  I haven't changed the camera angle order in these multicam shots - I followed a very consistent approach when constructing my multicams (not hard when there's only two cameras, and I knew from the outset which was camera A & which was camera B), so the multicam camera angles haven't been changed internally at any stage.  While grading some shots I have turned the b camera layer on & off for viewing at times, but otherwise, I haven't changed the order of these cameras

FYI: A friend of mine thinks this may be related to editing the camera order in the Source Monitor. He says it seems this is only affecting edits where the cameras have been edited to a new order. Also, Match Frame twice will match to the wrong camera when they have been edited.

Hi @Andrew C. Brinsmead - Thank you for the screen recording, that is strange.  Can you try one thing for me first backup your settings folder (24.0) and then go to Documents > Adobe > Premiere Pro > and delete the 24.0 folder.  Then launch Premiere Pro and let us know if that helps your issue.

I've worked out how to add the video (you'll note that I toggle the "insert or overwrite clips as nest button" to no avail)

Hi @Andrew C. Brinsmead - Would you be able to provide a screen recording of the issue you are experiencing?

(sorry - too many typos in my first answer! "Dang you iphone late at night!!!!😖")

What I meant to say was: 

Yes- with this production, when I "copy & paste" or "drag & drop" sequences from one sequence to another, sometimes my multi-camera angles will change, so I can't rely on "copy & paste" or  "drag & drop" to move around sequences in different projects in my production without changing them. To add to this, I can't perfrom an insert or over write edit from one timeline to a timeline in a different project in the same production.
