When I try to import an exported workflow, I get an "Unexpected Error". This doesn't happen all the time so I can't figure out what could be causing the error. The steps to create the situation:
1. Go to production list and export a workflow and save the file in my documents.
2. Open list in the new site and create a new blank workflow.
3. Click on import and select the file that I just exported.
4. Click the import button and receive the error.
This has happened before and I kept trying the export/import process until I didn't get the error. There is no description of the error. Just "Unexpected".
