The following issues are stated when config genworld settings are changed:

Untamed Wilds (untamedwilds) encountered an error during the load_registries event phase
java.lang.NullPointerException: null

Untamed Wilds (untamedwilds) encountered an error during the error event phase
java.lang.NullPointerException: null

Steps to reproduce:

1. Open untamedwilds-common.toml with Notepad++ in Windows 10
2. Change the following settings:

• #Controls whether to add Reeds and their associated items. reeds = false
• #Controls whether to add Bushes and their associated items to most biomes. bush = false
• #Controls whether to use Burrows to spawn Critters, instead of having them clog up the Spawns burrows = false
• #Controls whether to add Tree Orchids and their associated items. tree_orchid = false

3. Open Minecraft. The game won't open.

I would like to notice that I have also the configured mod and I've tried to change settings with it. If I change them BEFORE loading a new world, the settings are applied correcly, but the next time opening the game the game crashes and the same issues appear again.
