One of the travis test failures is an actual issue. I'll look into it.

@anyaelena -- actually is there a way you can fix the test?

[anyaelena]

@nllong yes, i'll look into it.

[nllong]

@anyaelena thanks. I think this can be merged down once you fix the failing test.

@nllong i verified locally that complete is working as expected. i don't have the test working but my working theory is that the introduction of the after_enqueue hook is messing with the test setup.

@anyaelena - i fixed the test to have it check for something else to ensure completion. I'm pretty sure that the queue is not getting updated because the simulations are not actually running in a queue so any triggers are probably ignored.
