Edited Issue: Package restore not working [41]

Add the nuget package for Clearscript V8 to a solution, build solution this completes with no errors.
Remove folder packages\ClearScript.V8.5.3.10.0, build solution this restores and completes with no errors.

remove V8 and replace with Clearscript without V8 dependancies.
Remove the folder packages\ClearScript.5.3.8, now the build solution fails because package restores fails:

Unable to find version '5.3.8' of package 'ClearScript'
