Two things I'm surprised I cannot find are: 1. An XP changing plugin that can increase or decrease XP gained from mining, smelting, etc. I've tried three so far. 2. A plugin that can change the default currency of villagers at the least (so it isn't emeralds), and optionally makes them have better, more interesting, trades. Have seen a few, but all are out of date and not working in 1.12.2 If anyone knows of a current plugin for either, let me know!
