Puzzles bugs

Ive had to restart this game 3 consecutive times, but not because my people die. Twice its because of the herb mastery puzzle, Ill drag a villager onto all 6 plants multiple times but it will just say they got better at healing, and not that the village understands the herb. And the most recent one is with the gong pieces. A random event came up while a villager was carrying on of the pieces, and when it caused them to drop it the piece completely disappeared.
