After try and error, i understand how to play mostly. However there are still quite a bug here.  The biggest bug problem is the one not allowing me to finish the quest. Like bomb the ... or board the ship. Example Black beard and someone else debt. I have to win several same battles. If lucky within 2-3 times i can finish the quest. But on my unlucky day the same quest i can do over 10 times and i still can't finish it.  Due to this bug, the faction attitude towards me have been in veryyyyy low negative now.  The quest to deliver something or go to location to meet someone got no error. The error seems to be only in combat mode which the game never recognize me winning it.
