So there were old threads about this that were locked because we were asked to wait and see if it got better.
Disqus still doesn't allow post editing most of the time and it still deletes posts. A bunch of people reported this before. As far as I have been able to tell, it really hasn't improved more than a tiny bit since these problems were being discussed a year and two years ago.
For that entire day yes, the forum posts would not show up. Even now, for some threads, if I click on the thread it only shows the top message, none of the rest. The rest are searchable, but do not show up properly otherwise.
That's because of a weird bug that causes links to threads to redirect to the second page of each thread. Hopefully there's a way to fix it!
Actually, when you access or google search any thread from a forum page other than 1, the site links to the page corresponding to that forum page. Hence, any thread shown here will have ?page=4 added to its main link (as opposed to the 'last post' button, which is of course wherever the last post was).
Ok, well that bug explains the latest problem. It still doesn't explain the deleted posts, the bad links, the broken editing function, the on-site links that direct you offsite and close your game, etc.
