Figure out what's up with niftany/rubocop

[ajkiessl]

It displays a bunch of general warnings and deprecation warnings every time it runs. It also sporadically stalls for me. Figure out how to clean this up.

It may be any issue with how it's configured in this app, or the issue might be with niftany.

It's been stalling for me when I run bundle exec niftany -a
