- The librarian's buy book trade now requires 11 to 12 books, down from 12 to 14 books before
- The farmer's buy arrow trade now sells 9 to 12 arrows, changed from only 5 arrows before. The 5 arrows resulted from a bug in the code where the minimum and maximum values for the arrow trade were swapped.
