I can't use the Bobblehead Collector's Stand (the large Vault-Tec metal look thing) in the Megaton house. I have the Medicine Bobblehead in my inventory, but when I activate the stand the game says ‘You have no Bobbleheads in your inventory.’ I also tried the Strength Bobblehead, which is the easiest to find in the beginning of the game, but with both Bobbleheads in my inventory I still get the same message.
I also tried the Bobblehead Display Stand (this is a different, smaller and portable wooden version) that can be bought from Moira Brown: this one work perfectly fine!
Is this behaviour a bug or a feature? Should the Bobblehead Stand (the original one from the Megaton house) be activated before it can be used somehow? Am I missing something? Or is this actually a bug?
