Hi thanks for getting back to me!   Screenshots taken today, showing the issue: This is how it appears when my cursor is above the shaded area. And this is how it appears when my cursor is over the shaded area.   That little letterbox of unaffected screen does not scroll with me - if I scroll down below it then the entire screen has that overlay, which seems to me like it must something going wrong with the article itself, and not an issue with how the browser is displaying it.     Additionally, all affected articles have this weird timeline section below them. I have not clicked on timeline to open this, it is always present at the bottom of the article. Bizarrely, these events are not ones linked to this article, and the affected articles have different historic events appearing there, and different numbers of them, but these events are persistant and do not change when closing and reopening the page, so they're not being randomly generated. The Lahey family page used for those screenshots always has the same three events appearing.   I have checked and this is not affecting any of my other worlds, so I don't see how it can be an issue on my end - if it was an antivirus or similar causing it, it would affect all worlds, not just this one. Additionally, I'm literally using a different computer now than the one I had when I first opened this bug report, and the issue persists, just as it does across different browsers.   While the overlay is present, I am unable to click any buttons or links - having tried carely possitioning things so I can click buttons/links even though I can't see them, nothing happens, so this overlay is stopped interactions with the page, rather than only being a visual glitch.
