Bug

We are seeing intermittent "bursts" of errors where the knex library fails to load lodash/clone:

Result: Failure
Exception: Worker was unable to load function process-reporting-messages: 'Cannot find module 'lodash/clone'

Any idea what would cause this?

I used version 2.4.2 and all was fine, probs your package.json is using ^ symbol next to your version number because version 2.5.1 was giving me that problem
