SharePoint (and Project Server) Shenanigans

While working on a migration project recently, we had reason to republish the OOTB Approval workflow to update the owner.

After this update we found that the OOTB Approval Workflow would not submit anymore.

After much head-scratching and googling I came across this social thread that covers the fault in some detail, the issue is caused by having KB2553322 installed on the PC with SPD2010 installed, as soon as we removed the patch and republished the workflow normal service was resumed.
