When attempting to diff a Blueprint that has been reparented when the previous parent no longer exists in the editor, a crash occurs. The crash is due to the editor attempting to reference the deleted asset for the previous revision in the diff. Even if this is not expected to work and the previous revision does not show the correct information, the editor should be able to handle this without a crash
Regression?: No
This also occurs in 4.16
