Are you sure you flushed your browser cash? It seems an empty move was submitted to the server, instead of Nf6. This could have come about by a bug in the script for that page, which I fixed two days ago: it was periodically refetching the game from the server to see if your opponent moved, and then automatically show you that move. But it should not have done that when it is your turn to move. For one, it would be pointless. But it caused the move that you just played on the board to clipped off the game again, when it refetched the game from the server before you could press 'Play Move'. This could have happened to you, if you are still using the script from before I fixed this (because of browser caching).
Anyway, I repaired the game on the server, adding 4... Nf6, and played my own move. Note that I am going to refuse a capture now (see chat).
