We fixed several workflow bugs:
Auto-advance Workflows will now auto-advance no matter what order you completed the tasks in. They will only advance once all the tasks are complete.
Task due dates Workflow task due dates are now generated relative to the previous visible task, ignoring any tasks that might be hidden by conditional logic.
Re-applying tasks If you move a process to a previous stage, any tasks that you completed in that stage will not reappear, unless it has been 1 year since you completed them.
This time limit is 30 days for leads.
