Power related error message

[Paragon]

I'm in the process of putting together a .stock file for the Broken Earth creatures so I can use the encounter builder with it, and I've gotten an error message on one (the BE "dragon", which is a mutated flightless eagle with pyrokinetic powers). I got three duplicates of the following error message:

"Attempt to access nonexistent child pick 'resPowers' from script
Location: 'eval' for Component 'Power' (Eval Script #2) near line 3"

I'm not recognizing where I'd even be finding this (since the "res" prefix doesn't seem to relate to any components in SW that I can find. And a search in the .user file doesn't seem to find that phrase at all.

Suggestions?
