Hmm... Are the animals supposed to ignore the tasty, tasty human, or is that a bug?
Also, I did not find any way to see the three bars for the human. Think I unlocked all the options.
They are supposed to ignore him for the first 90 seconds I think ! Then they should attack him if he gets too close (and I didn't get the opportunity to add an avoid behavor to the human ^^)
To unlock the three bars you must unlock the corresponding power in the intelligence category, then click the button that appears on the human panel ! I hope this one does show up for you :)
