Can't call custom library functions in my extended model (upgrading from 1.7.2. to 2.0.2)

From what I was told, a CI core commit is causing issues with the loader.

Try the code here (core): https://bitbucket.org/ellislab/codeignit...7258aa2bc0

or here (reactor): https://bitbucket.org/ellislab/codeignit...653e19b906


Let me know what happens, if neither one of these work I'll dig through the code and figure out what's up.
