recently in a forum post I included a game which is imported through the board like this :

however, after I had finished the forum, I tried to edit it and add more stuff, but then in the edit, I could see the chess board I have already put in the forum and it disappeared once I clicked finish editing pls tell me what happened and pls fix this
