Hmm.
Have you been to Ed's apartment, and gotten the items from inside the desk cabinet? I didn't have Ed take Bennett's items, so when I opened the drawer, there were items stashed away were in there. If you haven't taken them, perhaps Ed put the items you might require in there. I'm not sure though.
sirshermy: So I was playing my brother's copy and ran into this weird issue I wasn't sure if anyone else had. When Bennett was knocked out and I was searching for the fuses I accidentally had Ed take all of Bennett's items. Now that it is just Bennett I don't have his stuff to jimmy the lock on the tech room. Did anyone else run into this? Is there a work around or do I need to restart the entire game? No other inventory item works.
