So I was making my moves in a bunch of correspondence games today from a mobile device.
One of the games was https://online-go.com/game/7551275, but the m3 point that is occupied by my stone (black) was displayed to me as if white just played there! I was disappointed that I somehow missed such a big yose point, and responded at n2.
Right after that, I was redirected to my other game https://online-go.com/game/7789412, where n2 was displayed as my last move, even though I never played this move in that game!
When I went back to the first game, the m3 was black again, and n2 was empty.
n2 move played in a wrong game might be a client bug, but why did it show me a slightly modified position in the first place?
