Go into a correspondence game you are participating in, where it’s your move to play
Place an unconfirmed move
Estimate score
Press ‘back to board’
If I do this (latest version of Firefox, Win10) the UI thinks my unconfirmed move has been played, with text saying it’s my opponents turn, a circle on the stone, and the option to request undo (I’ve not clicked this, too afraid to mess up my correspondence games).
Kinda scary when it first happens. Going through the game with the move arrows at the bottom of the board fixes it.
I use Chrome on an HP laptop, and it hasn’t happened to me, but my experience may be outdated since I haven’t done this in a couple weeks. Too scared to experiment now.
Yes, it just looks like the move has been played, which is quite confusing. And when you refresh or go back to the game later, you see that it wasn’t played.
