Re-parenting a UMG blueprint

I made some changes to my code, but it broke some of my blueprints. They now complain about a missing parent class and I can’t open them. Is there another way to reassign the parent in a blueprint?

This happened to me once, and the only solution I could find, was to recreate the parent, change children and delete parent…

If the parent was renamed to something else, you can add an ActiveClassRedirect in the editor.ini

The parent class was moved to a new module which broke the blueprints. I fixed the problem by changing the name of the parent and created a place holder under the old class name long enough to get the blueprints to load in the editor. From there I assigned them to the new parents.
