At times, when Elden has clouds above him and you click him, he asks for you to hold a nail in place for him. The only option is 'Sure'. Unlike other villager interactions, Elden then repeats 'Sure.' and no experience is rewarded for interacting with him. This has happened multiple times to me using both Firefox and Google Chrome. I think it's a code error and not on my side of the deal, since other villager interactions work as they should.
