Unstable URLs for content

[nanxstats]

There seems to be a persisting issue with unstable URLs on the rinpharma.com website, specifically in the conference proceedings section: URLs that initially displayed specific talks are now showing different content. This issue has appeared at least several times before so I'm wondering if it's related to some randomness in each rendering or configuration changes.

Example:

• Current URL (showing one talk now, as of December 2023).
• Same URL archived (showing another talk in November 2022).

I would appreciate it if someone could look into this and correct the issue to ensure that URLs for the talks on the website are stable and consistent, which is essential for accurate referencing and sharing. Thank you!
