Expired task trigger the next one

Hi all,

I have the follow issue:

• Task 1 is completed not because task is done by user however because of expire status
• When the above happened, it triggers the notification to the performer of the next task (Task2)

The expired Task 1 should not trigger the Task 2 because it is not completed by the user. How can I solve? Someone has some idea that can help me please?

Thanks

Anamaria
