Question "Missing" existing script

There is navigation package inside the project and it provides NavMeshLink component, however I am unable to add this component to any game object.


It just does not exist there, but the script itself is available inside C# code, or if I try to add it with

GameObject > Add > AI > NavMesh Link

it actually adds gameobject with that component, but the script icon is white/missing.


If I enable debug mode and try to select script (with proper icon) it just breaks and throws error, while the white one seems to work.


I encountered similar behaviour once this month, but with some other script (I can't remember), but ignored that.
Can someone tell me what is going on?
Project is broken? package corrupted?

 

I haven't used NavMesh yet, but I thought that was just implemented at the top of the class within the

using UnityEngine."..."

type of reference?

 

Unity.AI.Navigation

, but the namespace does not matter I think, there is no problem in the code, file actually exists in the package, the problem is the editor is "broken" in some way and it can't recognize it correctly?
Hard to say, I don't understand this at all, so I'm looking for some tips from others.

 

Have you tried restarting the editor and/or deleting your Library folder and letting it re-import? That's my go-to when I encounter scripts that I know exist but don't show up where they should. Which happens too often for my taste, but what can ya do.

 

Completely forgot I can delete library. Yes, looks like this fixed the problem, thank you very much!

The funny part is the old script (previously added to scene) is still white and it works, but there is also the proper navmesh link script available
