Thanks for reporting this.
When it comes to suggestions to randomly populate worlds with various density so you get more monsters etc, as well as randomly generate new worlds - thank you, they'll be forwarded internally for the designers to consider.
When it comes to the CTD with your map - ideally the game shouldn't CTD at all of course. If you still have the map, could you perhaps attach a zip file of the mod's folder? That way, we could take a look at it and see if we can figure out what causes it to crash.
