Bug with Emissary Athena

Good day, dear developers!
After raising the flag of the emissaries of athens, and taking a quest to the harbor of thieves, when finding an ancient treasure, cups, boxes with legends, and lifting ancient skulls from the chests, which they received by completing the riddle after dug up the chest. Experience is not given to the level of the emisar, but only after the item is placed on the ship.
Before the update, there was no such problem, and in one quest you could get almost the fourth level of the emissar of athena, and now after the update, you can hardly get the 3rd level of the emissar.
