I got the info from the corpse, then headed to kash, after I got the mission from the imp I headed to the at st and started heading back the LONG way because I couldnt shoot the rebs ( they were up on the hill and it kept saying you cant see your target)I got to about 200 meters from the base and it says I failed my mission because I was to far away from my escort. I was 12 meters from it :/ Now all the imp guy says is isnt there someplace you need to be and tells me to bug off. When I go back to the at sts, nothing happens. Do I have to go get the info from the corpse on dath again?
