it took you this long to figure that out.......thats Sad....
Especially seeing as I literately shout it out to everyone. It's obvious that when r2fart2 accidentally wrote 129 instead of 124, Fr0stbyte, being an intelligent fellow, picked up on it, and created the false Fr0stbyte129.
I have a sugdestion for things you should add. You should replace all the blocks that have a wooden or stone texture with iron texture (iron fences, iron pressureplate , iron stairs, iron ladders, iron pistons, etc... ). That is my idea.
