Thanks for the info Xovian. I have been trouble shooting this, and I thought it was too many feats, or them having creature weapons, or being multiclassed. But it turns out If I just add a number of spell slots to their hide or items, then they start casting regardless of any of those other things. Iduno why since I had X number of preparations set already, but apparently they also needed spell slots. Hope that helps someone else out there.
