Can't change eye colors in CAS!?

Then you were lucky as many are having issues with defaults. I do know mods are an issue because they are patch related. Even a tiny bit of recoding can make a mod flinch badly and not a good idea to not get updates. NRASS number one complaint of people reporting issues with his patches was him having to remind people his patches needed removing before an update, and then not redownloaded until he had found time to update them. Often defaults have the same kind of patch level requirement seeing they are based often off EA meshes.
