Mmk. So. I've worked forever on this map, so today I decided to test it. I clicked the little test button then Boom. Feralheart.exe has stopped working. I looked through my particles, objects, and my_objects files and there were no duplicates anywhere. I didn't add in my own sky, music, or weather. I usually like to test it out before adding that stuff in. Anyway, I tried testing out other maps I've made, and they all worked. It's just THIS map. It's a city map, and I've have previous problems with city meshes, but those were only problems with the material file, and they've never had this effect before. Anyone know what's happening???
