Unbaloncable

Damn. I figured it wasn't in my world because I feel like I looked everywhere. Thanks for clearing that up so I don't waste any more time!

I am trying to find the prison POI to make my base but I can't locate it and I can't find any information about it. Is there still a prison POI in Alpha 20? I am using Navezgane pregen world. Any info on this would be appreciated!
