I've compared persons table with the backup and thumbnailPath are still the same, however content of those thumbnail files was changed tonight (26.1.) at 1am.

I noticed the same. The thumbnail path is unchanged but the actual thumbnail file is different.

Can you pick one person, change the face thumbnail and monitor if the face change to a different one tonight?

Sure, did it. I will inform you tomorrow.

I did exactly that yesterday and can confirm it hasn't changed overnight.

Seems the issue affects all feature photos set to people before v1.78.0 that are missing faceAssetId having only thumbnailPath.
The question is whether it happens again. The workaround is to set feature photo for those people again using current version of Immich.
I think there is no way how to revert the original feature photo thumbnail because of missing faceAssetId, right?

@alextran1502 No change tonight, I can confirm same as @Hixxey. It makes sense, newly set feature photo put faceAssetId to the persons table thus a thumbnail shouldn't automatically regenerate with different asset. The question is what was the trigger for persons without faceAssetId when this issue happened.
