An updated build with the following changes has been released.

Added:
+Una's "show evidence" option in the radio menu now tracks which evidence items you've presented, like standard colonists.
Fixed:
+The evidence score count at the end of the demo now tracks all evidence points correctly. The highest possible score is now 18.
+Duplicated dialogue in two colonists has been fixed.
+Colonists that wouldn't properly flag "the colony" evidence as used have been fixed.

Please report any issues on the issue reporting form.

Good hunting.
