Total delete and reinstall of the game fixed the issues for me. It's probably a 17.3 specific problem, but all random map gens I do with the experimental version of the mod causes 80%+ of the map to be radiation zones.
I'm finding that with 17.3E, and newest experimental build of the mod, it always freezes right after starting a game and getting in-game. 17.3 works unmodded, anyone else have this issue?
