How to Update from BETA-0.7.1:

With the introduction of Material Mapping, a new default GrowthModifiers.yml has been included, simplifying plant variant configurations. Here are your update options:

Option 1: Regenerate Default Configuration

• Delete your existing GrowthModifiers.yml.
• Use the "/rpg reload" command to generate the file with updated default values.

Option 2: Keep Existing Configuration

• You can retain your current GrowthModifiers.yml; the new functionality will not disrupt existing configurations.
• If desired, remove sections where the plant name ends with "_plant" to align with the new changes.
