Normally, attacking or boarding in third-person view should also revoke the privateer license (just like the trade license). It might be an oversight by the developers.

Oh, I was just going through the fifth quest "Hero of the Nation" where you had to take the baron to the Dutch province, and there I was suddenly attacked by a fort and a squadron. According to the quest, you had to sink the squadron and sail away. And I returned to the chevalier three times and he told me that he was disappointed and canceled my privateer patent. It turned out that this was because I attacked the enemy squadron manually in the first person, and if you attack from the third view from the ship - there were no problems. Probably this mod will fix it - thanks!
