It seems after the 10th comment, sometimes future comments are impossible to view. The numbered blocks don't appear and there seems to be no arrow button or anything else to reach them at the moment.

Does anyone know why this is?

One such example
http://illusioncards.booru.org/i...t&s=view&id=23809

Which contrasts to even very long comments like so
http://illusioncards.booru.org/i...t&s=view&id=18204

Booru.org doesn't allow that kind of change

I'm not the admin here but the list of commands you can do as an admin is painfully low
