OK, basically if I try to lower the percentage of mountains from default, the game will not start at all.
I have to leave everything as it is, otherwise the game will hang on the map setup loading screen.
I can't speak for Erebus Continent entirely, but it does use some of my code. There is a random bug in some of my stuff that causes an endless loop, and it happens too rarely for me to track it down. I've seen it once and then I never saw it again. Depending on map size, your computer speed, etc. you should wait at least 5 minutes though.
If any of you see the screen hang for more than 5 minutes, check the PythonDbg.log file after you force a shutdown, the seed value for the map should be in there and that will help figure out what might be causing this.
