`pickler pull <id>` works, `pickler pull` does nothing

[lolmaus]

Hi!

I'm trying to adopt a BDD approach for my project. Pickler seems to be an indispensable tool in a modern BDD stack alongside Yadda, Mocha and friends. Thank you for you effort.

When i first used pickler pull, it did download the only valid feature i had in the example Pivotal project.

Then i modified my project's tracker.yml to reference a new Pivotal project and added a number of features to that project.

Those features can be pulled individually with pickler pull <id>, but pickler pull fails silently.
