I was trying out various seeds and I found one that causes the game to freeze during world creation every time I try it, on two separate computers. In one of them I was running it from a batch file, so I have a nice stack trace to go with it:

I imagine that this is probably a ridiculously rare occurrence that I somehow managed trigger, but it'll probably help make the map generation slightly more robust. For now, I'm just going to use different seeds.
