Warning - the following content is a rant, and I make no apologies for it

Okay, do you have a Dev who loves crime?  You finally gave us an easy mechanic to rid our Civ's of almost all crime by building Orbital Prisons on our colonies.  Now suddenly in version 2.01 we can only build Orbital prisons on core worlds again.  If a core world has a significant number of colonies feeding it, the 20% crime reduction of a core world Orbital prison is overwhelmed.  I don't mind that you've invested in crime as a significant game mechanic, and I know there are other ways besides Orbital prisons to reduce crime, but they're not readily available in the early stages of the game.
