I am trying to access a workflow which was created by one of our clients.
When I click on 'Edit Workflow' and open the workflow I get the below (i.e. workflow empty):
Actual Workflow:
I am a Site Collection Administrator and Site Owner so permissions should not be a problem.
The workflow basically gets some data from the list and sets some tasks.
The client has informed me that the workflow has been saved and published multiple times.
I have also cleared the SPD2013 cache to no avail.
What can be causing this issue?
