This sort of issue has happened before, I believe it's related to T206190. These sorts of tasks usually get closed as "fixed itself eventually", but it would be nice to actually get this cache invalidation problem fixed.
For the record, purging the file description page, null-editing the file description page, and adding text to the path had no effect.

File:Benjamin Ola Akande.jpg was deleted after this task was filed, but the offending thumbnail is still accessible.

@AntiCompositeNumber I tried purging it with no success- my guess would be that it is not on cache, but on persistence layer for some reason. Let me make sure I can find it on swift and I delete the thumb.
The thumb is not on swift, so it is a cache issue.

I ran the following:

Which in theory should have purged all old versions of the file, but didn't seem to work.

I'm silly, the issue was on swift, not on cache:
curl -I http://ms-fe.svc.eqiad.wmnet/wikipedia/commons/thumb/8/81/Benjamin_Ola_Akande.jpg/120px-Benjamin_Ola_Akande.jpg HTTP/1.1 200 OK
But I cannot find the thumbnail on swift:
ms-fe1005:~$ swift list wikipedia-commons-local-thumb.81 -p '8/81/Benjamin_Ola_Akande.jpg/120px-Benjamin_Ola_Akande.jpg' ms-fe1005:~$ swift list wikipedia-commons-local-thumb.81 -p '8/81/' | grep Akande (no results)
, so to me this looks like a weird thumbor issue.

fwiw this issue was recently reported on https://commons.wikimedia.org/wiki/File:Anshu_Dikshant.jpg but I didn't get a chance to look at it before it was deleted.
The thumbnail not existing in Swift is certainly weird. https://wikitech.wikimedia.org/wiki/Swift/How_To#List_containers_and_contents does say that -p/--prefix must be before the container name in the command though.

That's not it, see we get the same output for a random file on the same container (I will update the doc to reflect this issue, it could be behavior of a previous client version):
ms-fe1005:~$ swift list -p '8/81/!Al_asalto!_-_comedia_en_dos_actos_(IA_alasaltocomediae00mont).pdf/page1-106px-!Al_asalto!_-_comedia_en_dos_actos_(IA_alasaltocomediae00mont).pdf.jpg' wikipedia-commons-local-thumb.81 8/81/!Al_asalto!_-_comedia_en_dos_actos_(IA_alasaltocomediae00mont).pdf/page1-106px-!Al_asalto!_-_comedia_en_dos_actos_(IA_alasaltocomediae00mont).pdf.jpg ms-fe1005:~$ swift list wikipedia-commons-local-thumb.81 -p '8/81/!Al_asalto!_-_comedia_en_dos_actos_(IA_alasaltocomediae00mont).pdf/page1-106px-!Al_asalto!_-_comedia_en_dos_actos_(IA_alasaltocomediae00mont).pdf.jpg' 8/81/!Al_asalto!_-_comedia_en_dos_actos_(IA_alasaltocomediae00mont).pdf/page1-106px-!Al_asalto!_-_comedia_en_dos_actos_(IA_alasaltocomediae00mont).pdf.jpg
And I checked that's the case for the relevant file, too:
ms-fe1005:~$ swift list -p '8/81/Benjamin_Ola_Akande.jpg/120px-Benjamin_Ola_Akande.jpg' wikipedia-commons-local-thumb.81 (no output)
