error CS2001 when downgrading a Project, after a Package has been imported



Repro steps:
- start up a new project with Unity 2018.2
- Open Packege Manager and import a new project
- close Unity 2018.2 and open the same project with 2018.1

Notice this error apearing in the console:
error CS2001: Source file
`C:/ProgramData/Unity/cache/packages/ -ui@1.8.2/Editor/Sources/UI/Interfaces/IPackageManagerExtension.cs' could not be found
error CS2001: Source file
`C:/ProgramData/Unity/cache/packages/' could not be found
Compilation failed: 2 error(s), 0 warnings

The error does not keep you from entering play mode, but doesn't disappear when you press clear either
If you reopen the project with either versions of Unity, the error will go away.

    actually not only this, but downgrading to 2018.1 causes scene prefabs get missing..
