The system currently does not handle this situation very gracefully.
If a user,
- Clicks on a question,
- Between clicking on the question and reading all visible comments the author removes the post,
- The user then tries to fetch more comments,
- This results in an error "Error fetching comments"
The user then has no idea why it failed until they try to refresh the page. If a question has been removed and someone tries to do any action on that page it should redirect them to the question removed by author page.
