So, I bought the game. Printed the rulebook off line to conserve the original rule book. Set up the game, read the online rulebook, glanced over the end scoring. Played many games on boardgame arena and understood it fully now. Set up the board game again and started to wonder where my little white numbers were on the conservation track. They were shown in the online rulebook. Checked the rulebook that came with the game and it showed a different way to score. Realized then that the online rulebook was an update to the rules. Had the game for over a week and had multiple plays on boardgame arena before I realized this difference. Long boring story. Only the truly insane will find it interesting.
