If you connect to a game from another computer than the one you just did your turn with, you will not see the changes/moves you have made(in the 2h file). However unless you do new changes (and press the end turn button) no new 2h file will be uploaded (and override the old one).

So redoing your turn in the instance you meantioned was not needed, you could have just closed the game.
