I unzipped the jar to get the classes, and then used jar to patch them in. I assume I'm doing something wrong, since minecraft refuses to load the map?
$ jar uvf minecraft_server.jar ix.class ch.class y.class
I've also tried implementing each class on their own, none works. :sad.gif:
I made my own lava fix, I believe llamacraft, this guys' mod and mine all do the same, its literally just commenting out one line of code. The file the code is in keeps changing, now its in z.class
I'll share my fix just to hold people over: http://minecraft.nom-nom-nom.us/lava-without-fire.zip
