Lets face it, the OP is using Gimp 3.0 
so anything is in the realms of possibility.
Maybe two possibilities.
The same image is opened twice, Image no, 2 is edited. File -> Overwrite is there but there is only the one file on disk
As: https://i.imgur.com/g6v57JJ.mp4
or If View -> New View is used, there are two image tabs of the same image showing. Edit no. 2 and overwrite. The edit is shown in no.1 tab but I suppose it could be overlooked.
Either way, the original image is gone for good.
