When you board the Black Pearl, all the lower decks are dark - less lighting, black wood. Thereafter, when you board any ship, all lower decks are still dark. The exception is cabins of different type to that on the Black Pearl. The screenshot is from my older game under Beta 3. The same is happening in Beta 3.1. I never played "Tales of a Sea Hawk" under Beta 3.2 so don't know if it was fixed there; it's not mentioned in "BuildInfo.txt".
