I'm playing with the latest beta patch and ACE mod (with all of the optional parts too). I'm doing the mission where you need to detonate the barricades. I've placed satchel charges on a barricade (I've tried placing 1, 2 , 3 and 4) and detonated the charge(s), but nothing happens to the barricade. When I had 4 satchels placed, I actually blew up a nearby wall, but the barricade still didn't have a scratch on it. Any idea how I can fix this or if I'm doing something wrong. Also, I tried placing them on both sides of the barricade.
Another quick question: how the hell do I disarm the IED without getting close to it?? I've tried shooting it, I've thrown a grenade right on it, which exploded right on it, tried throwing smokes on it. Nothing has worked, except walking up to it, which magically detonates it (despite the concussion of a grenade not doing that...). There are no bad guys left around the whole place. What do I do?
