Hi, thanks for the report on the bamboo rolling away. This should now be fixed making it much easier to make nests for the gorilla. You will also see information displayed on the female gorilla showing her needs.
This is part of a bigger update that should be live today or tomorrow. This interface along with audio and animation cues from the AI gorillas will help the player understand what the troop need to increase bonding. High bonding is vital to keep the troop together and allow it to grow with mating.
Regards,
Andy
