If I paste some moves from a website, eg. the Car Kann opening 1.e4 c6 2.d4 d5 3.e5 Bf5 4.h4 from chess.com openings (https://www.chess.com/openings/Caro-Kann-Defense-Advance-Tal-Variation), or I select "new game from clipboard" ... then everything looks fine. Stockfish will display the moves, evaluate, etc. all that good stuff. However , if I save it to a file and then try to open it, or I select "duplicate", then I get an error.
