So I see a lot of people have this problem. Has anyone solved it yet? The Vault 22 elevator thing doesn't work for me. I feel like it had something to do with the ncr support radio. The first time I used it boone disappeared for a little bit but he returned and then ed-e disappeared and has been gone ever since. even when the ncr ranger died he was nowhere to be found. it's been like 100 in game days. WTF!? I just want my pack mule back...
