Expected behavior

Both ore gen created by code or by json config should spawn in the world

Observed/Actual behavior

Only json config ore gen works

Steps to reproduce

https://github.com/Katalijst/Nova-ore-gen-issue
Build this project having two ores with the same config, and you will see only the one from the json appear in the world.
I've put model of flowerpot for the ore from json and chorus plant for the ore from code, both without cullface so you can see easily if the ore appeared in spectator mode.
