Find Unbound Kwills

[Precaryous]

In the quest "The Inkbound" it says to find the Unbound kwills trapped with other Kwillings. I've opened dozens of Kwilling cages now and haven't seen any (still stuck at 0/3). Am I missing something?

just to clarify:
1) make sure you're opening Kwilling Cages, and not Big Kwilling Cages. That quest predated the existence of the "big" cages and I think they're still struggling to catch up.
2) when you open the Kwilling Cage, the kwill pops out and falls on the ground, and you then need to click it, like picking up a potion or dropped vestige. It is NOT automatically picked up.
