Steps to Reproduce :

1. Download Mist Build 18
2. Download Terra 5.3.3-BETA from Spigot (this is 1.16 specific)

6. Open bukkit.yml

   world:
   generator: Terra:DEFAULT
8. Save bukkit.yml and close
9. Delete the world folder
10. Run
11. Enter the Server IP into Minecraft 1.16.5
12. Then you will spawn into a world with no structures
    Description of issue :
    Structures (trees...etc) won't load, just giving you a world with no trees and structures, cartographer villagers won't spawn.

This is (according to console) because I don't have Paper, yet I'm using a software that combines Forge and Paper/Bukkit/Spigot API because this is a fork of Mohist. (I was recommended to use this)
