After playing Heart of Gold, I can no longer use Construction to build Outposts in the default campaign.
Checked both levels of the campaign where Construction was enabled (Final level + Kira/Draven/Korvek) and in both instances, Mendeclaus will say, "The Construction ritual will not summon outposts in this realm..."
Restarting the game had no effect.
I imagine resetting campaign progress would fix the issue, but i'm not willing to test that just yet.

Not even an Artifact of Construction worked.
