In the Games conference, for some reason, all posts relating to Fallout 4 seem to have jumped to the top? But the only post with anything in it newer than 2015 is the "Return to the Commonwealth" one, as best I can tell. I thought there might be some sort of an edit in them, that's happened, but no. Nothing noted 'edited', or with a timestamp of 2017 in any way. And the one thing all have in common is that they mention Fallout (4) at all.

So...forum glitch, browser glitch in some obscure way, or easter egg for upcoming stuff?
