Harbingers and Empowered Timeline Blessings

OK, just defeated Heorot in his Empowered Timeline, got my Prophecy to drop, then out popped a Harbinger. I made the mistake of running away, forgetting that it might inherit Heorot’s big AoE attack. Live, die, and learn - right?

Well, since I did beat the Timeline boss, I was still expecting to get the Timeline Blessings. This did not happen. Is this to be expected now with the new mechanics?
