Game crashes on a world that used version 1.3, but was updated to 1.4 along with the config. It appears to be conflicting with Natura during retrogen. I created a fresh world and had no problems, but when I tried a world that I've been using before 1.4 to test mods, it crashes.
I've done some more testing and it seems that the crash is happening every time it tries to retrogen ores that were added to the config after the world was created.
