On a sidenote, the rate at which you get presents is astonishing, way better than pumpkins. I've got 2 fast explorers and 3 normal explorers on a long treasure search as much as possible, and collect the collectibles at least once a day, and so far I've been able to buy the rarity provision house, both recycling manufactories, and I bought 7 noble houses for 60 presents each, and I've already got enough again to buy a deerstalker hut. But yes, haven't regretted the rarity provision house for a second, saves you so many clicks <3
