There is still something wrong with the JDAMs. I'm with Peaches, there's something different about their behaviour now than I've experienced during my years of flying the A10.
On Mission 8 of the splendid Enemy Within 3 campaign you have to destroy 2 bunkers with GBU38s and for me, it took 4 bombs to hit them from 16,000+ feet. Rather bizarrely, 2 missed from one direction and 2 hit the target if I dropped them from the total opposite direction.
