Apparently she was selling her votes without being upfront about it, like you send her $30 SBD and she gives a 75 percent upvote. Not sure if that is 100 percent factual or if it was for that reason, but I assume there was something happening which led to her and several other whales losing their delegations.
You have two other whales who vote more often on your posts than her though, so I don't think it'll be a huge loss on your payouts, but it still sucks. Hopefully it is just mostly all of the bugs the site is having causing the issue, since I'm still experiencing them even after the update.
