Bug: Legitimate papers removed from release to release

Describe the Bug Hi, thanks for creating a great service! I am trying to download all papers from some CS conferences (e.g., AAAI, NeurIPS) but I'm finding that legitimate papers are removed from SS from release to release. I'm not sure how frequently this happens, but it's making it hard to reproduce my research results.

To Reproduce

For example, I found this paper in release 09112023:

{"corpusid":211530585,"externalids":{"ACL":null,"DBLP":"conf/aaai/DorrB0MHSCSZS20","ArXiv":null,"MAG":"2998331601","CorpusId":"211530585","PubMed":null,"DOI":"10.1609/AAAI.V34I05.6269","PubMedCentral":null},"url":"https://www.semanticscholar.org/paper/77e61c39ee59a03be8813f961cb1b327926dcce2","title":"Detecting Asks in Social Engineering Attacks: Impact of Linguistic and Structural Knowledge","authors":[{"authorId":"1752326","name":"B. Dorr"},{"authorId":"2632964","name":"Archna Bhatia"},{"authorId":"36235196","name":"Adam Dalton"},{"authorId":"1505503134","name":"Brodie Mather"},{"authorId":"1505542669","name":"Bryanna Hebenstreit"},{"authorId":"50629423","name":"Sashank Santhanam"},{"authorId":"1470639547","name":"Zhuo Cheng"},{"authorId":"145102721","name":"Samira Shaikh"},{"authorId":"1877429","name":"Alan Zemel"},{"authorId":"1791072","name":"T. Strzalkowski"}],"venue":"AAAI","year":2020,"referencecount":64,"citationcount":3,"influentialcitationcount":0,"isopenaccess":true,"s2fieldsofstudy":[{"category":"Computer Science","source":"s2-fos-model"},{"category":"Computer Science","source":"external"}],"updated":"2022-03-10T06:13:39.710Z"}

But it is not available today on API. Using third party wrapper (can get raw request if needed):

sch = SemanticScholar()
corpus_ids=['CorpusId:211530585']
sch.get_papers(corpus_ids, fields=['title','year','publicationDate','citations.publicationDate',
                                                    'venue','citations.year','citations.title','citations.externalIds',
                                                    'publicationTypes','publicationVenue','externalIds','citations.venue'
                                                   ])

It is also not available via webpage search, suggesting it hasn't been reidentified. https://www.semanticscholar.org/search?q=Detecting%20Asks%20in%20Social%20Engineering%20Attacks&sort=relevance Expected Behavior

Id permanency for papers.

Actual Behavior No results
