When mob griefing is set to false, Good Grief overrides the vanilla mob griefing rules by allowing some griefing events.
These include:
- Animal behaviors (sheep/rabbits eating, foxes stealing items, etc)
- Villagers farming
- Piglins bartering
- Snow golem trails
Disallowed events include:
- Creepers exploding blocks
- Endermen block theft
- Projectile explosions (ghast fireballs, wither skulls)
Good Grief has no effect while mob griefing is allowed.
