Hi,
I think the issue may be that you have the following start times for your 3 domains:
domain 01 : 0001-01-01_00:00:00
domain 02 : 0001-01-01_01:30:00
domain 03 : 0001-01-01_00:00:00
And since the simulation is only set for 1 hour, it's never getting to the start time for d02. d03 won't be able to run without the conditions for d02. Try setting all domains to the same start time and re-run the test. Let me know if that makes any difference. It's okay to start a nest at a later time, but it can't be before the start time of its parent.
