was showing
NaN:NaN.NaN
in white text over White’s user image.
This may have something to do with White being a bot,
but I don’t see anything unusual in the Game information.
I also don’t see that when I re-open the link, so I took a screenshot.
To anser your original question - and thank you for letting us know - it seem likes something just failed to load/download properly, which - reagardless of being in the 21st century - happens sometimes.
Do please let us know if the issue appears more often, but if not, I would not worry about it too much, could be just some temporary connection issues or whatever.
