Alien Turrets on a POI Build?

What happened to the turrets that are on all the POIs? I can't find them anywhere in the creative menu. If I spawn a POI in a creative game and multitool a turret from it, I get a player turret instead.

I suppose I could do a replaceblocks command but I doubt that's how creative mode is intended to work now.

 

They're in the Alien Blocks group. The red core.

 

Thanks, I had used them that way briefly after the change.
