Yeah, so sorry about that, it does suck.
It’s only for “legacy”[1] links that aren’t using the hashbang for privacy, the page will redirect to the hashbang. This causes the back button loop. If you create a new page or link to a new link, this shouldn’t occur anymore. Since the link has the page, and I posted this before I added the hashbangs, it will always have this issue unfortunately. C’est la vie - thanks for the feedback there.
[1] The project is less than a week old and there are already legacy concepts that need maintaining, that’s a first for me.
