Glitch – Virtual Villagers 3 Review

The ash stone will not appear after my fire has been burning, but whenever I set a villager near the campfire site, the waterfall and dry grass area, or the fire wood, they run away saying that the gem is too hot to pick up. I'm not really sure what to do and I cannot finish the door puzzle. Please help.
