This is exactly what uploaders mean by "patched."
I notice you're asking for a blog post related to And Then There Were None (2015) with “vietsub patched” — which likely refers to a version with Vietnamese subtitles that has been modified or “patched” (possibly a cracked or edited subtitle file).
This three-part BBC adaptation, based on Agatha Christie's 1939 masterpiece, is widely considered the definitive screen version of the story.
Some uploaders rename old broken subs as "patched" to get downloads. Verify by:
