Dear GungZA and Johnson and ra91111. i realy don't think they going to fix becaus there is loot inside the hidden spot on the roof of the school.
Other wise I can not shoot from there down. I have not try that but it seems that i have to hold my gun in prouns mode and at 1st person to shoot and see where im shooting at.
I will try it tho but that must get fixed so you not shoot down from there.
