I have a number of workflows that stop working whenever someone I work with publishes them. He doesn't get any errors when publishing. It's not all workflows but specific ones break every time he publishes them.
They start getting the error Failed on Start Workflow was Cancelled by the System.
If I go back in and publish without making any changes they start working again. I have no idea why.
We use Sharepoint 2010 workflows and Sharepoint Designer 2013.
As a side note, I had him try checking in the workflow files and then check them out. This didn't fix the issue.
