I have a case where user has two files with different Acoustid fingerprints that were mapping to the same Acoustid. But now if he removes the data and regenerates the acoustd fingerprints (that are generateed locally) remain as they were before but now they map to different Acoustids.
Under what situations does the Acoustid that a fingerprint is linked to change, is it only is exceptional cases where a bug has been fixed on the acoustid server or is it a general part of processing?
Previously both of the fingerprints below were incorrectly linked to Acoustid `950caf97-ddb2-4c6f-a36a-f542e7858c4f`
but now only one is.

As I understand the user is looking up by fingerprint, not submitting it. As all is based on similarity it is theoretically possible that a fingerprint matches a specific AcoustId now, then at a later point with new fingerprint submissions a different AcoustId exists that now matches the fingerprint a bit better.
If you do a fingerprint lookup the result is not always exactly one AcoustID, but if there are multiple below the similarity threshold all matching ones are returned. If you have the fingerprint for this case you could check whether the results maybe contain both the currently matches AcoustID and also the previous one.

You mean, both recordings were linked to the same AcoustID, don’t you?
That’s possible because a fingerprint of the wrong file was once submitted for the recording.
A fingerprint of the file Ντροπή τέτοιο παιδί.flac can’t possibly match one of acoustID `950caf97-ddb2-4c6f-a36a-f542e7858c4f` - its fingerprints are clearly not similar to fingerprints of the correct acoustID → [Compare fingerprints #14622166 and #86764183 | AcoustID](https://acoustid.org/fingerprint/14622166/compare/86764183)
However, I can imagine that a scan of “Η σύμβαση.flac” will find recording [Ντροπή τέτοιο παιδί](https://musicbrainz.org/recording/b2d697ee-c755-4960-a837-9435f331ab06/fingerprints) if nothing else is available. In reverse, I consider it impossible to find the other acoustID matching the generated fingerprint.
Look at “additional user-submitted metadata”:
→ [Track "6db214e4-cd6f-48ef-b848-ee3fcb4ee788" | AcoustID](https://acoustid.org/track/6db214e4-cd6f-48ef-b848-ee3fcb4ee788) (everything points to Ντροπή τέτοιο παιδί)
→ [Track "950caf97-ddb2-4c6f-a36a-f542e7858c4f" | AcoustID](https://acoustid.org/track/950caf97-ddb2-4c6f-a36a-f542e7858c4f) (a bit of a mess - the second entry is probably yours and should be submitted from a correctly tagged file as a recording 🙂 )
