Hi evry one. Virtual villagers 1:version 1.01, windows.

I got on the other day and i noticed when my healers chose to study the medical cactus on their own with out me dropping them on it cactus, after puzzle 8 "Herb mastery", well it says random thing like relaxing or pushing boulder when they are clearly studing the cactus. When i drop them on the cactus my self it says the right thing "studying medical cactus". I have uninstald and restalled many times and still the same. Plz help.
