Video proof must include the restart or the selection of a new game after a fresh start.
Within the last year, it was discovered that the RNG for the game (the order and selection of riddles, the password Marian gives you, the solution to Fulk's puzzle box, etc.) gets set on game start. This is either when you select a new game after a fresh start, or when selecting Restart from the game menu.
If you save on the very first screen and restore to that for new runs, then every run would have the exact same RNG. So, a rule was added that runs must begin after a restart, and not a restore.
However, without the restart being present in the submitted video, there was no way to verify this. This was my fault for not being clearer, and, to be fair, I wasn't consistent with it myself.
All existing runs on the boards will stay. Going forward, future runs will need to have the restart included in the video.
This leads to some otherwise impossible deaths. If you do Abby Monk first and create a save when you have the box, then play up to getting the scroll and learning the code; you can load back and get the fire ring before you're supposed to.
If you have it on when you cross the moat, the rider comments that it's a nice ring. You have that screen to take it off (guess they were being generous). After that the moment you put it on anywhere in the castle, you die. Even if there is no one around you.
The weirdest one is after you free the jester. You get a glitchy death scene where little John claims to have avenged you. (It's the same one you get for losing the staff fight).
