In playing Entrenchment (single-player), I noticed that the Advent Deliverance Engine no longer inflicts "culture damage."  The signal still fires and strikes a target (and the target must still be valid), but no effect occurs.  I used both auto-cast and manual targetting for a number of engines, striking both own planets, as well as enemy planets, to no avail.

Repro:

1) Make a Deliverance Engine

2) Fire it at a valid target (friend or foe)

3) Behold.

Notes: I *did* have two active starbases with Cultural Upgrades functioning, in case this has an effect.
