I think I am having same issue but I'm not entirely sure.
I am getting the "AR" on hellfires to show that it is ready and looking for laser code A. I have confirmed all laser and hellfire racks are armed and all laser code options set to A. Laser fires but hellfire remains at "AR" rather than seeing the laser and going to "AT". If you fire on "AR" missile of course sails and does not track the target at all (its not off by a small amount, it tracks nothing...)
It seems random when you get AT vs. not sometimes a helicopter will not ever get an AT, other times you can fire 4 in a row and then all of a sudden its just AR....I cannot find the variable causing the difference. If its the same bug, no problem, I'll wait. I believe we are talking about same thing, but I am just not 100% confident that its the same as what's been reported here.
Thanks
