Service Desk 7.3.1 - Process Designer

Version 7
    We have identified an issue with Process Designer after installing/upgrading to Service Desk 7.3.1.
    Modifying a Process that was upgraded to 7.3.1 will corrupt that Process
    Upon modifying a Process in Service Desk 7.3.1 that existed in your previous version you receive an error message which refers to ‘Transition Steps’ or a SQL error containing a reference to ‘lc_transition_step’
    The patch for this Problem is now available on Patch for Problem 4592 - Process Designer in 7.3.1
