[Steam v.5.0.0.0040] Paradise Of The Mind - Copperhead conversation don't start

Hello.
I killed Menzzago with all his minions and leave the orb unharmed, but I can't start the conversation with Copperhead.

1. I arrrived at splintered reef and kill welcoming party.
2. I went to the ship on the left bottom map area (the one where Copperhead go after the first meeting in the inn).
3. I went to the inn, spoke with Copperhead and then kill vampire lady, other undeads and released the principi.
4. I went to the area with enterence to the vault. Cleared exterior.
5. I went to the ship to speak with Copperhead. I convinced him to make some distraction.
6. I went to the vault interior. Clear the animancer vampire room, used first blood.
7. I killed the second vampire and used his blood to open the door.
8. Journal pop up then to check what is upstairs.
8. I went upstairs.
9. I spoke with Menzzago and kill him and his minions.
10. Journal pop up then.
11. I've left the orb unharmed.
12. I went to Copperhead but I can't start the conversation. He just wishes me luck, out of dialog's window.

I've tried to destroy the orb, after that Copperhead starts dialog normally & quest becomes complete. But I don't want to destroy the orb & want to receive an Animat figure from Copperhead as a reward.
