I am just a random user here, but when I clicked on your links, I got what seems to be the regular pages associated with your links. The problem might be deeper than the links themselves.
I know nothing about computers or coding though. All I know is from clicking on them and looking them up separately. I don’t mean to say I’m invalidating your experiences. I just mean to say the problem you describe might be deeper than the links themselves.
I am also sufficiently computer-ignorant not to know if what I’m saying is nonsense and the products of a moronic mind.
That happens to me sometimes too especially on long lists of suttas. I assume this is a feature (read: bug) of SC being a progressive web app: it’s trying to render things as-needed, but sometimes it’s a little late and the user gets a truncated document for a little bit.
