Still looking, but so far I don't have a Taskmistress that has a bow in her hand, so the arrow leaps to her fingers and flies off into no place. There is bow on her back, but it disappears in the "bow" animations like it's supposed to. if you have a Taskmistress with a working bow, please send it to lonespaceranger@gmail.com. Thanks!
Whoops! Found one! Never mind, but thanks anyway.
