I don't understand the load old game feature. In theory, this seems like a great feature: I can load an old game to review what I did wrong, try new things out, etc. I expected it to work similarly to loading PGN files in chess or Poker Tracker for poker: I would be loaded into a game where I could step forwards and backwards, and if I wished I could try out new lines. Instead, I have to pick a decision number, and from there all I can do is play it forward against a bot? This seems really tedious to me. If I want to play from a specific point in the game, I need to guess the decision number. If I guess wrong, I can't step forward, but have to exit and guess again. Am I missing something? Are there commands for stepping forward that I don't know about?
