CSS styles broken after updating Active Admin 0.6.0

Question

I was wondering if anyone might have some experience with this:

I updated Active Admin 0.6.0 (and four dependencies), and now the stylesheets aren't loading properly in the app, (broken on my machine and on staging)

Here's the list of gems (versions) with brief explanations

Installing activeadmin (0.6.3)
Installing kaminari (0.15.1)
Installing has_scope (0.6.0.rc)
Installing responders (1.0.0)
Installing inherited_resources (1.4.1)

Removing activeadmin (0.6.0) administration framework for Ruby on Rails
Removing kaminari (0.14.1)   paginator for frameworks and orms
Removing has_scope (0.5.1)   create controller folters based on your resources named scopes
Removing responders (0.9.3)  a set of responders to dry rails 3.2+
Removing inherited_resources (1.4.0)  make controllers inherit all restful actions

The offending commit only edited Gemfile and Gemfile.lock. Thanks for any help.

Answer 1

Try precompiling the assests with the following command. rake asset:precompile

Answer 2

For posterity:
The css problems were due to a css bug in Active Admin 0.6.0. Since I started with Active Admin 0.6.0, I unknowingly wrote my css to compensate for the bug, then when the bug was removed in 0.6.1, my css broke. Had I started on any other version of Active Admin, this wouldn't have happened.
When I finally upgraded past 0.6.0, I also had to fix my css.
