Drone base, player core. where is this stored?

In earlier patches, I could check a text file in the "shared" folder to see if a drone base had a player core
These files still exist for player made bases, but I dont see them anymore for drone bases that have been taken over
The "folder" for the drone base is still there e.g. "BA_GhostRider_DroneBase_7167"
but they just have the area data inside (which is obviously not text)
(and there is no 7167 text file or BA_Ghost.... text file)

So my question is: Which file contains the info...
