Okay, I logged out and cleared my cache (again, just in case) and logged back in. I can get to my locked entry comments from my inbox, and probably everywhere else as long as I don't try to navigate from my own page directly, but I still can't see my locked entries from my own page.

Edit: I can't see locked entries on my reading page either, unless I navigate there indirectly, say from my profile page or by typing into search.

This is weird.
