Artifact weapons cannot be scanned.

[Camnui]

According to this:

https://github.com/goonstation/goonstati...rgy_gun.dm

It's also syndicate scanner exclusive.

Note that, since it's it's part of /obj/item/gun/energy/, it inherits the properties of its parents.

Thus, artifact guns are scannable, but none of the other artifacts are since they just inherit the properties of obj/artifact

https://github.com/goonstation/goonstati...tifacts.dm

Note that it does not have a "mats" variable, therefore it is unscannable

that seems like something got updated and caused a bug, because the wiki specifically states that all artifact weapons should be scannable.
