I thought that was just superficial… that the rating system would treat it as a draw but it would display as B+0, but actually it seems that draws aren’t implemented even in rated games (New Zealand rules) as per Jigo / tie / draw is not recognized by OGS · Issue #657 · online-go/online-go.com · GitHub

So the higher rated player (Black) won points (1832.00->1841.90) and the lower rated lost points (1805.88 ->1795.20), while the game is recorded as a win (1) for Black and a loss (0) for white.
I don’t know why I thought it was only a display issue…
Bug since 2017 or before?
