That’s right, MoveToLocation is not a latent function and what it actually does is it requests a move and then instantly finishes. I’ll have that function renamed to RequestMoveToLocation to make it more clear.

But we just fixed it! (literally 10 minutes ago :D). I’ll make sure it’s included in the hot fixes.
