I read the spoiler for the statue as I was stumped
Drag an adult villager (not a nursing mom) up the path
to the door until he/she "Sees a good place to anchor the statue"
I have the bath, the plan,Level 3 Restoration, Level 3 Leadership, a tribal chief, a Master Builder.
But no matter who I drop at the top door [which has 2 of the 3 gems] nobody "Sees a good place to anchor the statue"
Am I doing something wrong or have I found a _bug_?
