Issue with HashRef attritubes

Hey everybody, I'm back for more!

Strange error popping up, with seemingly no cause: almost all of the
HashRef attributes (except for one) in my class are showing up as
"undefined" when I attempt to utilize them in my code:

Can't call method "exists" on an undefined value at lib/Namespace.pm line
285.

I know that all the formatting is correct, and the working attribute is
copy/pasted in the same format as all of the other similar ones; yet
somehow it is the only one that works?!

Moose, you do confound me so! Any ideas, guys?

Thanks,
Faelin Landy
