Are you using startboxes or fixed start locations?
Startboxes (if you used Springie):
CAI commanders start in the exact centre of the startbox. To move them with Springie type !addbox x y w h t.
-
x,y are coordinates 0-100
-
w,h are width and height of the boxes 0-100
-
t is the allyteam of the box, this is optional
To make it start in a specific spot make the width and height small then change around the position until it is in the place you want.
Fixed Start Locations (if hosting yourself with a lobby that is not Zero-k):
In this case the mapper has produced really stupid default start locations. You will have to switch to start boxes using modoptions and set up a startbox, the way to do this changes between lobbys.
