When I click on the small picture of the additional amethyst mine, my browser shows this error:
<Error><Code>NoSuchKey</Code><Message>The specified key does not exist.</Message><Details>No such object: jagex-6t9p/assets/img/external/oldschool/2021/newsposts/2021-07-14/ProposedAmethyst_Cave_Minimap.png</Details>
(Not exactly because Reddit treats _ and __ as code - and tries to format the picture name. But you've got the idea and I hope you'll check the path.)
Thanks for spotting it might be a problem with my HTML, I will get that fixed now. :)
