Bug with Sirin? (Tyranny)

After the capture of the first Spire, spoke with Mononom, decided to go to the Crossroads Letany. There in one of the houses accidentally found Sirin. She said something like: You sent for me Tune or the voices of Nereta?, though, as far as I can remember, it has not been sent, then I accidentally found. Then my Persian, she says: Come with me, you need to look out.
That's how I got Sirin in satellites that looked a little weird.
