The bug
A world can have an entity with the same UUID in each dimension. This causes various issues like MC-151270, MC-153319, MC-184266, or MC-195337.
How to reproduce
- Add an entity with UUID 0-0-0-0-2cfcc in the overworld.
/execute in minecraft:overworld run forceload add 0 0 /execute in minecraft:overworld run summon minecraft:item_frame 0 0 0 {UUID: [I; 0, 0, 0, 184268], Fixed: true} - Add an entity with UUID 0-0-0-0-2cfcc in the nether.
/execute in minecraft:the_nether run forceload add 0 0 /execute in minecraft:the_nether run summon minecraft:item_frame 0 0 0 {UUID: [I; 0, 0, 0, 184268], Fixed: true}→

A world can have an entity with the same UUID in each level
The bug
A world can have an entity with the same UUID in each level. This causes various issues like
MC-151270,MC-153319, or MC-184266 since the game assumes there are no entities with the same UUID in the same world.How to reproduce
- Add an entity with UUID 0-0-0-0-0 in the overworld.
