in game history i'm assuming...?
"Both replays and reverts are performed by viewing the game log and clicking on the icon in the 'R' column on the right hand side."
Has this been recently re-disabled? I seem to have no "R" column.
It should still be visible - it has't been disabled.
Okay - so if you're as stupid as I am with technology (I'm 38, so I have an excuse), here's what I missed and how it might help you:
From the game viewer there is a link "View Log". This is where you can find the "R" column with the replay icon.
If instead, you go to the history button in the player and click on "Log view" hoping to see an "R" column, you will be disappointed.
So, "View Log" is good, but "Log view" is bad. I don't know about all these subtle distinctions tom ;)
