Hi @jnovick

Some tests are failing, can you check these errors?

[jnovick]

Yes, I will take a look.

@jnovick, Any update on this?
Thanks!

When I initially looked, I could not find anything wrong which frustrated me. I just looked again and got the tests running locally and they all pass. I merged master in and it seems to be fine with appveyor as well. I think the test failure before must have either been a fluke or unrelated. Thank you for your follow up reminder since i had forgotten about it.
