Assets Do Not Compile When config.assets.digest = true

[lynndylanhurley]

In my production environment, the only way I can get our assets to compile into a single file is by setting config.assets.digest to false. This is not ideal because 1. we want the digest fingerprinting behavior, and 2. the asset_sync gem requires config.assets.digest to be set to true.

Here is my config file:
