Complete Parcel Selection, Buffering, and Report Workflow

We're experiencing an issue with the Complete Parcel Selection, Buffering, and Report Workflow

 

 

The error is during the report generation "There was a workflow error running activity: Exception has been thrown by the target of an invocation.

 

Unable to load specified workflow from instance store.

 

Unable to load workflow running instance data.

I'm wondering if anyone else has had his issue and knows how to fix it?
