SPD 2013 error workflow

Error received for no apparent reason when creating workflow.

Errors were found when compiling the workflow. The workflow files were save but cannot be run.

Solution:

Clear out Website caches from %username%\appdata\local\microsoft\websitecache\

Note to clear out the contents of the site folders, not the folders.

After this shut down the SPD and restarted and everything worked again.

Also deleted contents of %username%\AppData\Roaming\Microsoft\SharePoint Designer\ProxyAssemblyCache , which might contributed.
