(not my game)
The winrate and score graphs were accurately generated, and the scoring process worked fine. Using the “Estimate score” button, it briefly says “[unset] by NaN” before being replaced by “White by 19.51”. Looking at other recently-finished games (example: Freundschaftsspiel), they seem to be working fine, though also show the “[unset] by NaN” behavior (someone might want to fill in a default “please wait” field there ).
