A bug was reported where clicking the assignee tag under a topic title redirects users to a 404 error page. AlexD10 provided steps to reproduce: open an assigned ticket, click the assignee tag, and observe the 404. The expected behavior was a user profile popup, similar to the whisper feature. nat asked for clarification on the URL and assignment type, leading AlexD10 to confirm it was a topic assignment causing the URL to change from β/discuss/t/test-bug-report/56570β to β/t/56570β. nat then confirmed the issue likely stems from a subfolder installation of Discourse, which AlexD10 verified. ted acknowledged the report and confirmed the fix is merged in the discourse-assign plugin via PR #420. AlexD10 thanked the team for the update and resolution.
This is probably topic assignment which leads to the same topic but URL changes in this case for example from β/discuss/t/test-bug-report/56570β to β/t/56570β after clicking on assignee tag.
