Glitch industrial induction furnace. (Minecraft)

play the 1.5.2 build, there are with the ic2 addon for induction furnace and gretech. this oven works buggy: throw stack something any that want to melt, and he first to one bar, then 4, then 16 and after 64, and zasidannya Stuckey still almost full left. take the ingots, after melting continues, but the number of bars does not change, it remains continually one, and when you take them and fill up my inventory, they disappear. I don't know how to fix it, not versed in Java and in General I'm just a user. but the build I really like, and I don't want just because of this glitch to remove this Assembly and play other.
