Import dir 'FO4_Scripting' and unknown namespaces

[Zebrazilla]

Trying to compile this and see that there's an imported directory called 'FO4_Scripting'. Can you shed some light on what this is? Do I need it to compile?

I'm also trying to open this using papyrus-lang in VSCode and are getting errors regarding unknown namespaces, here's an example from Context.psc:

[Build]: unable to locate script Papyrus:Project:Context
[Build]: unknown namespace papyrus:compatibility:external
[Build]: unknown namespace papyrus:log
[Build]: unknown namespace papyrus:versiontype
[Build]: unknown type userlog
