REGRESSION: In 4.24, there was a fixup process that would allow the soft reference to remain valid. This seems to be missing in 4.25
Moving an actor to another sublevel immediately breaks soft references to it.
The user can manually fix the reference by re-selecting the actor, but there used to be a way to have this done automatically.
The reference to cube is no longer valid (has an error).
There's no existing public thread on this issue, so head over toAnswerHub just mention UE-94157 in the post.
