For the past week or two, a handful of matches have had keycards and traps turned off, and almost all of the items can't be grabbed. No switches (levers or neighbour clocks) do anything when used, either, though buttons work fine.
It basically makes it impossible to win as an explorer, as you can't pick up keys.
I would have assumed cheats, because some of these games have had cheaters in them, but not all of them - this still happens when there's no cheaters in the game.
