@ChuckHastings @rlratzel @aschaffer This affects you guys, so please take a look.

rerun tests.

This affects you guys, so please take a look.

Unless you've changed the signatures of sort_and_shuffle_values() or renumber_edgelist() I (at least) should not be affected. It seems that you have not changed the signatures. Please correct me if I'm wrong, Thanks.

=> No changes in the API, but if you call sort_and_shuffle_values() or renumber_edgelist(), they will fail without these bug fixes. This will not affect you till you're ready for testing, but this is necessary for the test to succeed.
