Based on this query, there is inconsistent behavior with the comment ids.
For instance, the first ID is listed as follows:
The second is listed as follows:
The third is the same as the first (post link, no comment link), in fact it seems that any comment lower than around number 23,000 doesn't have a link.
Were the way comments are handled changed such that old comments are unable to be rendered as a link? Having a link to the comments would be helpful if it could be added.
