sylvanas bugged

hello on deathwind sylvanas is in the river ouside undercity and i cant give her the love bracelet,anyone knows what should i do?

I couldn't find a bug report for the Gift for the Banshee Queen quest. If you want, go ahead and create one in our bug tracker

She's in that water like for a week now...
Not only finishing quest is impossible but also achiv for killing her is impossible to complete cause of her swimming time.
