1.9.2 Video thumbnails lost when moving video files

[FKCapitalism2]

If photo has thumbnail and file being moved using thumbnail view in XnViewMp then it does not re-generate thumbnails again just update path in the catalog, however for video files when i move them using thumbnail view in XnViewMp say create new sub folder and move videos there then thumbnails are not saved and have to generate again.

I can't reproduce, Thumbnail is always re-generated for image or video files
