[Season] Unusual Wanderer Pollock

(Sorry, I don't write very well in English, so I use a translator.)
There was a problem during the quest. The quest required to run through five points, using maps. When I got to the fifth point, and used the vantage point, the quest just disappeared. The quest did not continue, it was not in the quests or the black spirit. The quest to return to Velia did not appear, and I did not receive the quest reward. I threw the cards out of my inventory, but I couldn't get them from the black spirit.

 

You should be able to get the map pieces back with Black Spirit. BS is also responsible for giving you the last quest that ends in Velia and get the Pollack's Strange Box.
But first you gonna have to talk with Rosa Kloko, Santo Manzi and Igor Bartali. They all stays in Velia.
