I submitted a similar bug report previously where the wrong post context can sometimes load when clicking the link to respond to a specific comment. A /comment/… url.
Now I am also sometimes getting the wrong post title and body simply navigating to posts themselves from the main feed. Notice how in my screenshots both pages have the same url https://beehaw.org/post/721194 and comments, but one has the incorrect title and body.
I think this is a very important issue to resolve in case a NSFW post is mistakenly loaded for someone who does not wish to see NSFW content.
Good details, thanks for the report.
