Didn't work. Changed it to 10, 1000 even, unfortunately had no luck.
I have the Object Layer Mask = Character (player). Also tried some other layers.
It also never actually returns an object. Which might have something to do with it? Even when I walk in front of it / when it should hear me.
Edit: So I got it to return objects now. Although the AI is still stuck in its place.
Once it returned its object, I made it switch over to seek, which immediately allows him to move.
Which of course still means that the wander etc doesn't work at all.
