Problem with case sensitive in loading controllers

I have about 100+ controllers, 80+ models and 50+ libraries and probably well over 150+ views. A crazy crazy enterprise platform. I upgraded from CI 2 to CI 3.

There was no way lol, that I was going to change all the filenames from lowercase to uppercase. Nope, don't have the time for that silly stuff.

You can change codeigniter 3 to revert back to lowercase. Of course and before anyone jumps down my throat, 1) you have to know what you are doing and 2) you better know how to maintain your installation should any problems occur and 3) don't forget to change for future versions.

The changes I made work well, haven't had a single issue and the application runs like CI 2.0.

So yeah, you can side-step any issue here. You just gotta know the framework code.
