Braked Animation when an en passant capture is made

[Denner6]

Ok, I know that chessGround does not have any chess logic inside it, I using chessJS to do the chess logic for en passant capture, all working fine. Except for the en passant animation when clicking (not dragging) , the animation is braked, because i use fen: <Fen> to load the chess board without the captured en passant pawn. I tried to use animation field. but don't see work. How to can i fix it?

I watched you video a few times. What is it that is broken about the animation?
