Incorrect Villager Trades

Incorrect Villager Trades bug only happens when playing in single-player mode, traversing between two worlds.

For example, from going into World A, saving and quitting to the main menu, then entering World B, World B villagers will have some vanilla trades retain making emeralds trade show up which aren't supposed to be there. It also applies to the same worl A as long as player returned back to main menu from world.

To fix this, restart the game if you ever jump between your saved worlds.
