Hi @mpiatkowski, thank you for your post and I am sorry that you are experiencing issues, and thanks @aparrish for chiming in! Let’s try a few troubleshooting steps in this thread first to have a better understanding of the issue together.

@mpiatkowski I tried to reproduce the issue you are experiencing and I was not able to.

Could you try opening your document in a private or incognito window to help us narrow down the potential cause? Could you also try connecting to a different network or disconnecting from your VPN (if applicable)? Sometimes account performance issues can be related to internet security/speed or browser issues. These steps will help us eliminate that possibility. For help with opening an incognito window, please see this community post.

Additionally, WebGL might be causing an issue with the graphics card on your computer. Can you try toggling WebGL off? This can be done by selecting View > Rendering > Use WebGL and un-selecting this option. For help with disabling WebGL, please see this Community post.

If the issue persists then, could you please provide the following information in order for me to have a look?:

Screenshots encompassing the entire screen illustrating steps leading up to the issue.

Thanks for your help and patience!

I am having this exact problem.

Steps to reproduce:

Create a new blank diagram
Use the Flowchart shape set
Create two containers (A and B) with ASSISTED LAYOUT ENABLED
Create two Process shapes in container A, connect them inside the container with an Arrow Line
Create a third Process in container B
Link a Process from Container A to the Process in container B using another Arrow Line
Use Ctrl-A keyboard shortcut to select all
Observe how the select highlight / blue line does not include the Arrow Lines
1. Arrow lines not visibly selected
Use Ctrl-C keyboard shortcut to copy the selection
Open a new blank diagram
Use Ctrl-V to paste the selection
Observe how the internal line between the two container A processes is preserved/copied, but the cross-container line from Process A to Process B is omitted

Now, the workaround -- disabling assisted layout:

Return to the first diagram
Disable assisted layout on both of the containers
Press Ctrl-A to select all
Notice how all lines are highlighted/stroked to indicate selection. Even the Container labels have a blue selection-stroke to indicate it is properly selected
1. non-assisted-layout containers with shared line
Press Ctrl-C to copy
Open a new blank document (or reuse the previously created copy-to blank document)
Press Ctrl-V to paste
Observe how all lines are copied and pasted successfully, thanks to disabling assisted layout:
1. Copy-to showing all lines preserved

Another way to reproduce this bug (use Duplicate instead of Copy/Paste):

Prepare the Copy From diagram as described above, including Assisted-Layout containers
Right-click the diagram tab, select Duplicate
Observe that the newly duplicated diagram is missing all cross-container lines when compared to the original diagram tab.

Hi @James D, thank you so much for chiming into this thread and my apologies for the delayed response!

Thanks!

Another workaround is to surround both containers with a large assisted-layout container. Surrounding with a third Assisted-layout container allows tab duplication and copy/paste to carry over all lines and shapes as expected.

This has drawbacks, though, as enabling assisted layout will cause your internal containers to move to fit the assisted layout grid - see the bent cross-container line below.

Surrounding with a third Assisted-layout container allows tab duplication and copy/paste to carry over all lines and shapes as expected.

Surrounding them in a Non-Assisted container does not help at all - the copy/paste omits the line or the entire internal containers, depending on how you copy/paste.
