Villagers price fix

After the 1.14 update, players found a bug that allows villagers to drop prices to 1 emerald per item, making the game too easy. My suggestions for a fix: 1. Make one-time bidding on rare items (books, diamond armour, diamond tools). 2. Take into account only the largest discount, that is, if you have a 30% discount, for example getting a new 15%, nothing will change. I think this would greatly increase the value of diamonds and also give a reason to explore the world.
