MacRumors.com is not effected. This and previous times, it was when I click on the forum link from that page, I run into this.
I'm finding that sometimes, a page now loads correctly, just posted in the game forum, but from that page, when I selected this forum, I got the same issue, no formatting. So I tried duplicating the tab that was open, produced a good page of the gaming forum, and from there, selecting this forum from the list of forums, I was able to get here without it appearing. Sometime when this happens with the bad format, the page takes forever to load and sometime it does not load, or as mentioned sometimes it opens without any formatting... 🤔
