npm issue?

package.json

{
  "name": "npm-test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "lodash": "^3.10.1",
    "rquery": "^2.0.8"
  }
}

steps.mkd

1. Create a folder called npm-test and place package.json in there.
2. cd npm-test
3. npm install
4. ls node_modules. Observe that lodash and rquery folders are there.
5. Open package.json, change rquery version from ^2.0.8 to ^3.1.1.
6. run npm install to update packages.
7. Observe that this line gets printed out after running npm install: lodash@3.10.1 node_modules/lodash -> node_modules/rquery/node_modules/lodash
8. ls node_modules. Observe that lodash is no longer there. This makes any code in the project that runs require('lodash') break. (ex: node test.js using the test.js file in this gist)
9. Run npm install again, look at node_modules and observe that lodash is back there.

/* run `node test.js` */
