Sorry for nagging, but anyone have a view on the co2 percent? It takes like 6 hours for me to reach 10 percent wich is deadly. The crew dies at 100 percent in the game. The boats were supposed to be able to stay submerged 18 to 24 hours, and 24 hours gives me like 40 percent. Around 4 to 5 percent seem a critical value medicaly, so it seem sensible to divide the percentagevalue given in the game by 10. I couldn t be able to do scapa my way if I had to breathe the boat before 6 hours..
