Removing ads and in app purchasing issues warnings

I have removed unity-ads and in-app-purchasing from the package manager,
why not, i do not use these packages.

when i run the game 'play' I get a lot of warnings:
The assembly search path `E:/development/games/ECS/quadtree - b3/New Unity Project/Packages/com.unity.ads` does not exist

The assembly search path `E:/development/games/ECS/quadtree - b3/New Unity Project/Packages/com.unity.purchasing` does not exist

etc lot more simular warnings..

not a big issue, but i wonder why ?

Unity 2018.3.0b10
PackageManagerUI 2.03

thanx Rob

 

ah restarting the editor, no longer issues the warnings

 

Had the same thing with com.unity.analytics package. "The assembly search path doesn't exist" after importing package/changing version.

Just restart the editor.
