Libraries no longer have base library visible by intellisense in visual studio

[Xenthio]

Describe the bug

In visual studio the base library is no longer linked or referenced by other libraries, this compiles fine in s&box but causes difficulty in visual studio (such as it removing what it deems to be "unused" using directives and breaking compiling in s&box on save)

this recently broke a few days ago (as of 21st of may, i first noticed it on the 19th).

To Reproduce

1. Create a library.
2. Try access something like the Button Class or NetworkHelper.
3. Watch visual studio be a pain.

Expected behavior

It should correctly be able to reference things in the base library like it used to.
