I've never noticed this before, only the last day or so. When typing a quick reply in Chrome I can't make paragraphs (hit enter and the blinking text cursor disappears), and editing to try to create paragraphs occasionally crashes the site in any browser tabs it's open in.
If it's some obscure thing I've done to my computer then my bad, but I only notice the issue on MMO-Champion and again, only for a few days now.
The pages all appear to be fully loaded and I'm not having any other issues.
