I successfully dug up the Grail as a hero, but I didn't check if it appeared in the inventory. I came to the town, clicked on the Capitol... and the game didn't offer me anything to build. I checked the hero's properties, and it's empty - there's no Grail! What should I do now?
For reference, I've attached the map and save file. The Grail should be with that one hero who is on the adventure map in the Castle.
