Description

First up, I'm new here and new to the software however I'm really impressed with QGIS, well done all!
Ive been editing a large data set of roads and every now and then when I save my edits a road (Vector) randomly disappears and its data is attached to some other vector (typically one I've just been editing).
See attached images before and after I hit the save edit button. Note I have screen recorded everything If this would help.

Note: I've speed up portions of this to reduce boredom factor. If theres anything you need slowed down just let me know the time on the computers clock (top right of screencast).
Spoiler alert, this movie has a sad ending.

I'm struggling to understand how to replicate the issue here. Would you mind prepare a small dataset, attach it here and describe the exact steps that lead into the issue? Thanks!

I see there is the yellow /!\\ icon on the bottom right in both of them. Are there any related error messages in the log?

In #7472-17 you can see a way on how to replicate what probably is the same issue described in this ticket (or at least a similar one). You can use the sample project attached there https://issues.qgis.org/attachments/6000/test19edit.zip

Ignore the missing layer error when loading the project, then be sure to enable the avoid intersection option in the snapping options dialog.
