When you try to use the Cooking Stove in the kitchen of the Abandoned Restaurant (not too far from the Vagabond's camp), either nothing happens, or the perspective switches to third-person and you have to cancel the interaction to get back to normal.

Also, there is a chance that the Tiger cigarette card in the upstairs office will disappear before you can get it. Reloading doesn't make it reappear, only restarting Fallout: London.
