Ok so I spent the last hour collecting all of the Snow Globes i go to Lucky 38 and because i killed Mr. House the robot that buys them off of you is just a normal Securitron Mk II I cant put them on the stand in the Presidential Suite. Has anyone got a way to solve this or is it a glitch that is going be around for a while?

The Girl robot Goes away when you kill mister house.... Same with other named robots.
