It seems like a global issue when trying to view a game review or analysis after a long end game. Should certainly be simple to recreate and address. It's been an issue since I joined the site.
I will say, you can click download, copy your PNG, open a new analysis and load that PNG. This will at least let you analyze and review your game, although it doesn't add that to your completed/analyzed games from my experience.
I wanted to analyse a game I finished one minute ago. Then the game was away and not in the archive. That is really bad
