Hi Neocles!
I think I found the cause of this. I was having the same problem so I started messing around with the location values and it worked.
What I think is happening is that 0,0,0 is an unreachable point and so the AI wont move.
I changed the value of the X in the destination:
I used 5040 because of the size of my Landscape as you can see here:
If I set X to 5040 it will go to the top of the map:
And if I set it to -5040 it will go to the bottom:
So its very likely that your problem is that the location you are telling the bot to go is unreachable.
I hope this helps
