"Poaching" No Longer Works

Under the "Opportunity" ideology, the last option called "Poaching" does not work.  The first screen snapshot below shows that I have used a culture point to select that option.  The second screen snapshot shows that Iridia, a world that I just captured, is not a Core World meaning that it does not have a Governor, which means that "Poaching" did not work.  This has happened with a number of previous worlds that I have conquered, but it took a while before I was sure that it was not working and I got annoyed enough to post about it.  For what it is worth, "Poaching" worked well in previous test versions so it looks like a change you made in the latest version has broken this.
