Issue/Introduction

My process is stuck in a step during runtime, even though the process validated successfully.

Steps to Reproduce:

1. XOG in attached process to reproduce the issue.
2. Add Assessor on the create view for Change Request object.
3. Navigate to Home->Projects and open an existing project.
4. Go to Change Requests and create new CR.
5. Process will trigger and Action Items will be sent, which can be responded to via Organizer to allow for process to move forward.
6. After AI was responded notice process gets stuck in the Approved step with status Running, but bg-ca.log throws an error.

Note: This process is based on change request object and you must populate the project manager and Assessor of the change request at the time of creating a new change request.

Expected Results: It should allow process to move forward.
