Autocomplete and errors fail on sub-packages

[DreepyYunky]

Sorry, but why does autocomplete and errors fail when importing a subpackage (a package within another package)

I'm using Neovim and I'm demonstrating this through the Xlib library in X11 and I have at line 12 I set a clearly wrong value but It hasn't given me any errors

Maybe this is an error? Some kind of oversight?

There is no such package to import. core:x11/xlib is not a thing in the core packages.

Can you import packages that are in core and complete them, such as core:fmt?

[DreepyYunky]

You're right, X11 was in vendor, not core.

It should have given me an error though.

[DanielGavin]

I do not control that. I just get the errors from odin check, but since that has no line position, I cannot show the error.
