Review button gone.

I was looking through my past games to review a game against Mittens, and the review button is gone. For some reason, it shows the accuracy of both me and Mittens as "0", despite Mittens having an accuracy of 92.8 on one of my other games. It also shows the accuracy of me and my opponent as "0" for variants games, which had previously showed nothing due to the engine only supporting regular chess. I am assuming this is a bug, and hoping it can be fixed soon so I can review my games against Mittens.

How are you accessing the site? I'm able to see the button on your games against mittens and can click the accuracy column to run a Review

I am accessing it via PC. Here is a screenshot of my games against Mittens in the archive.

Instead of showing the "Review" button, it shows both accuracies as "0".

There's no button because there has previously been a review completed; that's the bug. If you click the value it will load and run a review
