Nah, Airdrop isn't a baby griffin level. The raven should be able to fetch the items in that level.
I just tried it again and it is working fine for me.
If you post your code I'll try it at let you know if I have the same problem or if there is something funny in your code.
If I try to have the raven fetch an enemy or a friend it says, "I can't carry that." what exactly is the raven saying?
