When an HR record is created the workflows will not attach and run.
Release or Environment
Due to a custom change made on the state flow record.
State flow record - /nav_to.do?uri=sf_hr_case.do?sys_id=15d129b3df23210068c37a0d3df26313
This state flow record is being called by an base system business rule - /nav_to.do?uri=sys_script.do?sys_id=19d129b3df23210068c37a0d3df26313
and there is a starting state and ending state missing.
Reverting the state flow to the base system one will help resolve the issue.
