Not critical but tiring bug (I think bug or better omission). After renaming blueprint with a thumbnail (created before by Asset Actions/Capture Thumbnail) thumbnail is cleared. Clearing is not necessary, because this is same blueprint (in this case actor bp), with same object etc, just name changed. With a lot of actor blueprints for rename what is sometimes required, this is no good.
Thank you.
Edit - topic changed, thumbnail gone when asset is moved to different directory.
