I loaded up a quest from b15 on b16, to test for new bugs, and while I was testing, I encountered this bug (I think). When Link walked into a "Pay for Info" room, the message string appeared like normal, but when I bought the info, the sound of a message scrolling sounded, but no message string was visible! The string is visible in b15, so it might be a bug in b16. I'll update this as soon as I make a test quest in b16 and check if the "Pay for Info" room works then.
UPDATE: It doesn't work even if you create the quest in b16, it still doesn't show the message string just plays the sound.
