Block4Block 3.1 Patch Notes:
Features:
- Cats now prevent Creepers from exploding within 32 blocks and will hiss at the creeper letting the player know it's not a bug.
- List for blocks that should be explodable by intended game mechanics including beds and respawn anchors. All blocks not on this list will be immune to these kinds of explosions. List of affected blocks at the bottom.
Balance:
- Phantom Elytra drop chance increased tenfold.
- Improved Iron Golem's aggression towards intruders + removed conflict with anti-cheat checks.
Minor Improvements and Bugfixes:
- Coordinates in boss bar are now instantly updated when using /coords [on|off] command
- Named mobs will no longer despawn, even if the name comes from an anvil-renamed spawn egg
- Added String as alternative for breaking TRIPWIRE.
- Added missing spawn eggs and updated /chickenbonus command message
B4Block.org:
- Crops now have a chance to spread every time they grow. Released as its own plugin: https://www.spigotmc.org/resources/crops-spread-naturally.114288/
