Good morning sir!
Im not a super inteligent person or anything but i think those spoilers are more likely related to the latest officially released chapter (also known as Chapter 1103 of the One Piece manga)
As you can see, the tweet states "Ch. 1103...", which could be a mistake coming from who published it, instead of 1104, he typed a 3 instead of a 4, and since we are talking about human beings, we all know we can make these kind of mistakes.
Also, if im not mistaken, the actual content of this post reminds me of the events Chapter 1103 of One Piece has gone through. I hope we can find the best solution for this matter so all of us can enjoy this two decades and a half long story without much problems.
My thanks.
