Ok I'll post here as I still feel incredibly bad about it. Sorry for missing the boss loot folks my only defense (and it's a weak one) was that when I changed toons for the fight my primary PC decided that it didn't want to play NWN anymore so I had to relocate to the machine in the sleeping kids bedroom and play in the dark (if in case you wondered why I suddenly developed the typing speed and ability to spell of somebody with no fingers). The worst thing about it was thinking back I remember walking past the remains and not bothering looking at them as I assumed (for some insane reason) that it was from the matrix. I'm going to blame it on PC problems and playing at 2am.
I think a big problem was that usually several people looked at each loot on the run. To me only the person popping should look. This way you don't run into things likes this. That others looked and did not pick it up makes them just as guilty. When you pick up loot there is a tell stating "Found XXXi". If no one saw that after a few looked at it then that is the first clue that they were not grabbed. Like you I had to log to get tools. When I got back I saw someone post there was a Rad Gen so I assumed someone who looked grabbed it. The rest of the group should have caught it.
