Maybe this is related to the size of .pgn file. Smaller .pgn files from twic seems Ok.

0 wins, losses, and draws but with one game means that the game in question does not have a result. Can you check the offset and verify in the original PGN that the game has no result. I have a test case for this logic.

gbtami commented 7 years ago

The problem is not the last "move" line with 1 "games" but all lines being 0/0/0 in the position 1.e4!
