Update:
Looks like there's /practice/custom API now to replace /play/computer.
Example:

Unfortunately practicing doesn't allow you to resign & analyze the game 
Hello,
I have bookmarked a bunch of links I was using for playing computer at a specific position.
For example:
Najdorf with Bg5 for Black:
https://www.chess.com/play/computer?moveList=e2e4%20c7c5%20g1f3%20d7d6%20d2d4%20c5d4%20f3d4%20g8f6%20b1c3%20a7a6%20c1g5&fen=rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR%20w%20KQkq%20-%200%201
Or Scotch Game:
https://www.chess.com/play/computer?moveList=e2e4%20e7e5%20g1f3%20b8c6%20d2d4%20e5d4&fen=rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR%20w%20KQkq%20-%200%201
However yesterday I noticed they don't work anymore, they always open the initial position.
Did you change something in the API for playing the computer?
Is there a way for me to create new links so I can figure out how to write a script and convert my old links into a new format?
Thanks!
Sergey
