You've misunderstood the puzzle, which is probably my fault to be fair. You have to reverse the 3-day letter movement. The letters in the riddle move forward every day, the terminal says it's been 3 days, therefore reverse the positions of the letters by 3 to reveal the riddle. Also, you must convert the solution to the riddle into numbers, not the riddle itself. Sorry for the confusion, I honestly regret making that puzzle the way it is. It's a bit too complicated compared to everything else.
