We have a handful of workflows created in SPD that set a particular managed metadata column. These were working until the installation of some cumulative updates. Particularly, the June 2012, August 2012, October 2012, December 2012, and the February 2013 updates were installed, and we believe this is when the workflows stopped working.
When I look at the history of a workflow, it shows as completed, but it has only done some of it's work. It sets values for some columns, but will not for any managed metadata columns.
If anyone has any ideas, I appreciate them.
