Blueprints reported as changed when changes made only in parent

[Louspirit]

Hello,

When editing a parent blueprint (like adding a variable) and saving, it triggers a source change in all its children's blueprints.

I have had this bug for quite some time, and I'm tired of having to diff one by one to revert them all finally.
👉The diff in children shows no modification, or 'Move node None is right revision'.

Maybe we can't do much, but it is worth asking. 🤔
