Ancient Constructs not showing up in the economics screen on their tab

[Droll (OP)]

At this point in my game I have taken control of a power and propulsion (40%) artifact and the colony has 40m people living in it.

Why does it still not show up on the "ancient constructs" tab? (its just empty)
Note that invaders were only enabled 30 years into my game which is currently year 52 with one active rift at 100m diameter (it's launched two waves so far)

Edit: I would also like to ask how the ancient construct bonus is distributed (if at all) in the case that there are multiple neutral races with multiple populations sharing the same body with the construct.

Doesn't show for me either, I think the tab is just broken. The boni work though.

I can answer that: Everbody gets the full bonus, both on the body and 10% everywhere else.
