oilyrag: 2 aim arrows appeared ...... cue elvis ....
There are always 2 aim arrows on the screen. The big one with the yardage & elevation, and a small one on the mini-map.
The small one is normally contained within the borders of the mini-map, mostly. The Koele CTTH small aimers are able to roam a great deal outside the mini-map thus appearing on the big screen. Its simply the borders of the mini-map need adjusting to rein in the wayward small aimer.
