Take a look at the engine evaluation (and computer analysis) in this game
At plies 36 and 38. There was a jump from 99.0 to some low value twice. I am aware that engines evaluations can have jumps, but this looked too suspicious as in both times it was exactly 99.0, the jump was so large, and the correct eval is unlikely to be that.
Could this be a visual bug? Local engine in browser is giving the same evaluation.
