❓ Troubleshooting & Frequently Asked Questions
❓ Frequently Asked Questions
Q1: Why are bats not spawning in my world?
Answer:
- Check the active GameRule value using
/gamerule better-bats:bat_spawn_weight. If set to0, spawning is completely disabled. - Remember that surface spawning requires nighttime or dark forest overhangs (
Sky Light <= 7) over valid spawn blocks (#minecraft:bats_spawnable_on).
Q2: Why are changes in better-bats.json not taking effect in my existing world?
Answer: Values in .minecraft/config/better-bats.json set baseline defaults for NEW WORLDS ONLY. Existing active worlds store their configuration inside the world's level.dat GameRules. To update an existing world, use /gamerule commands in-game.
Q3: Why are resting bats dropping Bone Meal items on my floor?
Answer: The GameRule better-bats:bat_drop_guano_item is set to true. By default, this is false (bats fertilize crops directly without dropping physical item entities). Set /gamerule better-bats:bat_drop_guano_item false to stop item drops.
