So i run an MCsharp server http://www.minecraft.net/play.jsp?server=d39ef0b79d7dba1d74eec6dbdff88e71and ive been wanting to use Omen to make more levels for it, but ever time i use omen it will never allow me to save the world i render as .dat files and only .mclevel files. i was wondering if anyone knew what the fix was, or if theres a .mclevel converter to .dat.
