Plugin and Datapack List

none

Actions to reproduce (if known)

hold or equip a null head

Paper version

1.18.2 latest

Other

if you hold or equip a null head it crashes the server

[Doc94]

How can you get a "null head"?

[e-im]

This sounds very much like a creative thing. If you're not able to do this in survival, it'll be a wontfix. There are practically an infinite number of similar/related issues.

Creative servers should use a plugin to filter what is possible with creative mode. such issues are not generally fixed by paper.

[electronicboy]

CraftMeta should probably try to be sane, but, that's the general extent of what we care about in regards to malicously crafted data, illegal data either should be captured using a creative protection plugin, or, not created by users, vanilla does somewhat good by just not caring about the data, but, there's generally 0 care that stuff won't

huh interesting, it only crashes paper, not spigot or etc
