Interesting! I haven't gotten that far, I'll have to see how it pans out. I'm not sure of Larian's intentions in allowing you to knock her out and rescue her later, whether it's intentional or some kind of bug. It seems quite confused right now. So I'm not super surprised that her recuitment is buggy. Hopefully they'll give us a more straightforward option to recuit her (on a good playthrough) at some point.
