Indeed it should activate either if you sink/capture a ship OR if you get the respective book in some other way.I thought these tutorials were only activated when you sink a ship? So you can't keep out of battle to wait for the timers to expire because they only start after a battle.

But I had to make a slight change, cancelling the timer if you get the book to complete the tutorial. So once you've received the initial message and questbook entry, the timer starts. If you ignore the message then one month later it disappears. If you go after the book and complete the tutorial then it should stay. I've put the updated version place of the old version in post 18. If you already downloaded "quests_common.c", please download it again.
