I put out an open invite as White that was accepted by an opponent. I played 2 Nf3 after 1 e4 Nc6. But after looking at my games the game against this opponent had disappeared and one against JJdiana was started, with me supposedly making the move 1 Nf3.
I think the first opponent deleted the game I was playing with him, the game reverted to being an open invite, and the RHP software confused the two games so as to have me moving 1 Nf3.
