There is a bug in cargo that busted the name list functionality for items, resulting in wrong/random items being returned for {{Il}} (item links).

A fix for them to behave similar to before has been deployed, the underlying bug still exists though. If you see item links showing the wrong item despite being correct in the source text please null-edit the page. For other item link errors (red text) see the template for details.
