Me and my friend's world had a strange glitch, it summoned Dragon's Breath balls, similar to the fire charges. Sometimes this creates a particle effect similar to the Dragon's Breath in the End, and if you walk into this particle cloud you take damage and the death message is "Bob was killed by Area Effect Cloud using magic". You have to wait a few minutes until it disappears. Sometimes it doesn't summon the cloud of particles, it just stays there. If anyone has more information on this and how to fix this, you can tell me and it would be appreciated.
