I've been working on this map for about a week now, and today, I'm having quite some trouble with it.
Whenever I try to open the map in Hammer, it crashes on me before the mod selector box pops up. A little while ago, I tried using Worldcraft 3.3, and it opened fine then, but I went and configured it all correctly, and now it's doing the same thing.
Download the map here and see if it opens for you.
I didn't put this in Problem Maps because I don't think it's actually a fault in the map, I'm pretty sure it's just Hammer acting up. Also, who ever checks those maps?
