"[SEVERE] Permission node 'creep.irongolem' in plugin description file is invalid" error

Hey guys!
I was just compiling my plugin, and it compiled fine, but I get this error on my permission nodes:

Code:

2012-08-09 15:26:46 [SEVERE] Permission node 'creep.irongolem' in plugin description file for Creep v1.7 is invalid

My plugin.yml is here: http://pastebin.com/pME6mmmk
It only happens on the newest permission nodes, not the first couple I put in.

Any help would be appreciated.
