It has happened multiple times now, the site does not allow the player to properly refuse bad counting from the opponent. Usually I can just remark what is properly dead but often it does not allow you to, nor refusing the count allow you to go back into the games and just capture the dead stones.
This happened in the arena game linked below, not only my opponent wasted time playing unecessary moves, but he also marked my alive stones as dead and did not mark his dead stones as alive. I undestand that this was dfue to poor understanding of the game, but ity could be solved rather easily if the site's counting system was more reliable.
