The creaking ignores the hostile mob cap. This lets you cause humongous ammounts of lag if you collected a crazy ammount of creaking hearts.

Steps to reproduce

• Create a superflat world with preset minecraft:pale_oak_log,minecraft:creaking_heart,minecraft:pale_oak_log,minecraft:creaking_heart,minecraft:pale_oak_log,minecraft:creaking_heart,minecraft:pale_oak_log,minecraft:creaking_heart,minecraft:pale_oak_log,minecraft:creaking_heart,minecraft:pale_oak_log,minecraft:creaking_heart,minecraft:pale_oak_log,minecraft:creaking_heart,minecraft:pale_oak_log,minecraft:creaking_heart,minecraft:pale_oak_log;minecraft:plains
• Set time to night
• Pray

Observed Results

• The creaking spawns endlessly untill your game is absolutely unplayable
