Description
The bug
If a zombie is provoked by a second zombie using commands, the second zombie will join in the fight against itself, causing it to attack itself repeatedly. Zombie villagers, husks, zombified piglins, wolves, blazes, silverfish, endermites, aggressive pandas and bees also exhibit this behaviour.
Originally reported by malon. See also this discussion on Reddit.
How to reproduce
- Summon two zombies that cannot move:
/summon zombie ~-2 ~ ~ {UUID:[I;0,0,0,1],Attributes:[{Name:generic.movement_speed,Base:0}]}
/summon zombie ~2 ~ ~ {UUID:[I;0,0,0,2],Attributes:[{Name:generic.movement_speed,Base:0}]}
- Summon a snowball, belonging to the first zombie, above the second zombie:
/execute at @e[nbt={UUID:[I;0,0,0,2]}] run summon snowball ~ ~3 ~ {Motion:[0.0,-0.5],Owner:[I;0,0,0,1]}
→
The first zombie begins to attack itself
